No accented letters in window title bars, dash and hud.

[Coeur Noir]

Hi,

I've noticed problems with accented letters since few days in 16.04 Unity :

- in window title bar, accented letters are replaced with « square symbols ». It happens in all softwares when windows are not maximized. Once maximized, accented letters are correctly shown ( in top panel, for example : Vidéos, Téléchargements… ). Wrong display of accented letters comes back once window is un-maximized.

- in dash, accented letters are ignored. If I type « démarrage » on keyboard I get « dmarrage » in dash

- [edit] same behaviour in HUD, no accented letters there either, which is very annoying in french.

I did not have those behaviours some days ago.

Another screenshot showing the « bug » with accented letters :
http://img15.hostingpics.net/pics/722577Capturedu20160708012213.png

I've also noticed that bug does not happen if « folders » are opened using the bookmarks in Nautilus.

[Coeur Noir (coeur-noir)]

Here is another example with firefox and the same window, non-maximised (accents not ok) and maximised (ok)

[Coeur Noir (coeur-noir)]

HUD suffers same problem as Dash :

if « sélection » is typed on keyboard, it becomes « slection » in HUD.

[Coeur Noir (coeur-noir)]

well it's not only esthetic problem, but a real usability issue : you can not use accented letters in dash & hud search - which is a real pain for many languages…

…glad it's triaged but what am I supposed to do now ? I'm still having the issue on my up-to-date 16.04 - so probably 16.04.1 by now…

Any log or else I may provide ?

[Coeur Noir (coeur-noir)]

I did a reinstall from 16.04.1 iso and problem is solved…

…but that does not help knowing what caused it though.

[Coeur Noir (coeur-noir)]

Problem is back ! ! !

Added Pango in the list because of those last lines here on that screenshot…

[Coeur Noir (coeur-noir)]

( just a question : following your invalid notices I removed the other project in bug description. I wonder why it is invalid for HUD as this bug actually affects HUD - accented letters can't be typed in )

[Coeur Noir (coeur-noir)]

test@Asgard:~$ cat /etc/environment

test@Asgard:~$

Shouldn't be there also
LANG="fr_FR.UTF-8"
in that file ?

[Coeur Noir (coeur-noir)]

Added LANG="fr_FR.UTF-8" to /etc/environment → no change…

[Andrea Azzarone (azzar1)]

1. No, your /etc/environment looks just fine.
2. Unity is responsible to render the HUD, so Unity (Ubuntu) is the correct project to blame
3. env | grep LC looks suspicious, I'll look into it

[Coeur Noir (coeur-noir)]

Thank you.

Out of inspiration I did

env | grep LC

on my running fine 14.04 installation and it also returned nothing.

[Coeur Noir (coeur-noir)]

« 2. Unity is responsible to render the HUD, so Unity (Ubuntu) is the correct project to blame »

Ok with that - but it's neither Unity nor HUD that render the window-title-bar ? Compiz ?

[Andrea Azzarone (azzar1)]

Unity renders the window title bar too.

[Coeur Noir (coeur-noir)]

Ah, my ignorance, sorry ;-) Thanks.

[Coeur Noir (coeur-noir)]

Don't know if it can help… I've just notices accented letters appear right in chromium window title bar - while it's still wrong in firefox title bar…

Question : can this bug also affect language displayed in some dialog boxes like for example « open a media » in VLC, which remains in english ?

[Coeur Noir (coeur-noir)]

Same problem since today with Ubuntu 14.04.5 LTS
http://hpics.li/d86599b

Just before noticing this problem with accented letters I had a problem with some dead keys used in french for ^ and ¨
I was then unable to type ê or ï ( only ^e or ¨i )
I had to go to system-settings → language → and re-enable ibus as input method - I say « re-enable » because I think it was enabled by default.
Something may have changed this setting ?

[Coeur Noir (coeur-noir)]

It seems Ibus has nothing to do with ê-keys. I put back none as input method and ê or ï or î work as expected.

[Coeur Noir (coeur-noir)]

I used bleachbit 1.12 that day on ubuntu 14.04
→ https://answers.launchpad.net/bleachbit/+question/376577

and I also used it on ubuntu 16.04 - version 1.10-1 from ubuntu universe repository.

Not a problem. LANG is set, so the LC_* categories inherit their values from LANG.

@Coeur: You'd better remove the 'LANG="fr_FR.UTF-8"' entry from /etc/environment, since it's already set in /etc/default/locale. And please don't start messing with LC_ALL.

Seems like the common denominator is Bleachbit. I have no idea what that tool removes, but fear that it removes too much. :(

Can you please show us the output from these commands:

gsettings get org.gnome.desktop.input-sources sources

gsettings get org.gnome.desktop.input-sources current

[Coeur Noir (coeur-noir)]

On ubuntu 14.04 ( where I'm facing the same problem now )

gerald@Asgard:~$ gsettings get org.gnome.desktop.input-sources sources
[('xkb', 'fr+oss'), ('xkb', 'fr')]
gerald@Asgard:~$ gsettings get org.gnome.desktop.input-sources current

gerald@Asgard:~$

I think my environment file is ok :

gerald@Asgard:~$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
gerald@Asgard:~$

[Coeur Noir (coeur-noir)]

test@Asgard:~$ cat /etc/environment

…all same as in 14.04

[Gunnar Hjalmarsson (gunnarhj)]

Ok, thanks, it confirms that the "French (alternative)" keyboard layout is effective.

I just realized that's it's not a (pure) typing problem, but a display problem, which indicates that it's font related. You may want to rebuild the font cache using this command:

fc-cache -fr

(it takes a few seconds to execute)

[Coeur Noir (coeur-noir)]

fc-cache -fr

…no, does not fix.

About bleachbit I ask a question on its forum https://www.bleachbit.org/forum/what-are-files-deleted-regarding-%C2%AB-translations-%C2%BB-ubuntu

[Coeur Noir (coeur-noir)]

Here is a list of items to delete from bleachbit 1.0-1 on one « working fine » ubuntu 14.04 machine.

[Coeur Noir (coeur-noir)]

Now on the same machine, I installed bleachbit 1.12 from bleachbit website and run with the same settings, here is the huge list of items to delete.

( this time I did not go further and so did not delete those files - my ubuntu still works fine )

[Gunnar Hjalmarsson (gunnarhj)]

OMG! Some things are just utterly stupid. Is there a way to "undo" whatever bleachbit messed up?

It sounds as if you have confirmed by now that it's not a problem with the default Ubuntu installation. So if I was you, I'd simply reinstall and forget about bleachbit.

Don't know what else to say.

[Andrew Ziem (ahziem1)]

If you can narrow it down to specific files that were deleted by BleachBit, you can have apt-get reinstall the affected package to undelete the files.

Also if you can figure out which files should not be deleted, I can work on whitelisting them to prevent them from being deleted again.

Indeed, but that person won't be me. In this case it seems to have affected both typing (there shouldn't be a need to clear all IM related environment variables on Ubuntu - the default setting "IBus" should work fine) and displaying of certain characters, and this makes it extra complicated.

Not sure where I'd start. Generally it's a bad idea to delete selected package owned files instead of the packages, since they will be reinstalled at next package upgrade, so the whole concept with bleachbit is fragile and controversial.

I can mention two examples, which I find extra weird:

* The ubuntu-docs package only installs English content pages, together with symlinks to pages in other languages. Content pages in other languages are installed via language-pack-gnome-*-base packages as part of the language support for respective language. So there is already a space saving arrangement in place. Bleachbit still interferes and removes those symlinks in /usr/share/help/*/ubuntu-help! (Similar seems to be done unnecessarily for a few other help packages as well.)

* Bleachbit seems to remove locale definition files in /usr/share/i18n/locales which belong to the locales package. Why? If you want to affect which locales are actually generated, then the proper way to do it in 16.04 is to edit the /etc/locale.gen file. In general: Never mess with glibc provided packages if you don't really know what you're doing, or else bad things can happen.

Another thing which struck me is that several directories in /usr/share/X11/locale are removed, possibly jeopardizing the X system in an unpredictable manner and certainly breaking the XIM input method for those who want to use that.

My principal contribution to Ubuntu is about helping out with various localization issues. I monitor and patch a few packages and provide l10n/i18n related support. I suspect that various subtle issues which are reported are due to the use of bleachbit, and this bug report seems to be an example of it. Bleachbit probably causes quite some headache out there.

So I have my reasons for advising against the use of bleachbit, and I'm not inclined to spend more time on it.

…ok… I'll go for reinstall as I am not skilled and talented enough to narrow down the specific files that are needed / not necessary to delete.

16.04 was only for testing, quite empty.

14.04 is my actual place of working and will be tougher to reinstall.

But at least I know how to do that.

Thanks Andrea & Gunnar for time, (trying to) help, explanations and pieces of advices.

16.04 → get back to normal situation ( with accented letters ) thanks to Bertrand0 here https://forum.ubuntu-fr.org/viewtopic.php?pid=21586183#p21586183

I'm still struggling with 14.04…

[Coeur Noir (coeur-noir)]

…and finally found how to fix in 14.04 too !

Helped by the command provided by bertrand0

dpkg-query -S \*/{translations,locale,locales,locale-langpack,i18n} | sed -r 's/, /\n/g' | sed -r 's/:.*//' | sort -u | sudo xargs aptitude reinstall

I've finally noticed that xkb-data and xkb-data-i18n were not at their initial trusty version. Months ago I had manually upgraded them to fix a problem with somehow inactive Right Ctrl key. So I've forced back those packages to their actual trusty version, and now accented letters are back in title bars, dash and hud ( after relogging ).

[Gunnar Hjalmarsson (gunnarhj)]

Great that you are about to resolve it! Wish I understood which files affect this, but I don't.

[Coeur Noir (coeur-noir)]

I assume xkb-data and xkb-data-i18n are good candidates, since as soon as I reinstalled them, accented letters were back.

Yeah, sounds like a hint to the BleachBit folks.

(hadn't seen your comment #46 when I posted my comment #47)

As regards those two packages, and based on your latest comments, I assume that reinstalling was a no-op in 14.04, since you had a higher version number installed than was available in the archive. That in turn would explain why the files removed by BleachBit were back only when you downgraded.

[Andrew Ziem (ahziem1)]

October 2016 there was a major commit in BleachBit to how localizations are cleaned. This came out in BleachBit 2.0. Is this still an issue?
