Cannot find UnicodeData.txt

[Daniel Cordeiro]

Hi,

Every time I run unicode searching something like, for instance:

$ unicode a acute

I get the following message:

Cannot find UnicodeData.txt, please place it into
/usr/share/unidata/UnicodeData.txt,
/usr/share/unicode/UnicodeData.txt, ~/.unicode/ or current
working directory (optionally you can gzip it).
Without the file, searching will be much slower.

Unicode still works and show the results, but I'm wondering if UnicodeData.txt shouldn't have been included in the package.

This error never happend in the previous version of Ubuntu.

Status changed to 'Confirmed' because the bug affects multiple users.

Install the unicode-data packages fixes this. Which is a on the unicode packages Suggests: list.

[Daniel Cordeiro (dcordeiro)]

Hum.. the insteresting thing is that I though about that.

But when I went to synaptic package manager, right-clicked on the unicode package and saw the list of suggested packages, the unicode-data option was not enabled for installation (even if the unicode-data is not actually installed).

Do you think that it can be a bug in the unicode package description (that does not allow synaptic to see the unicode-data package as a valid installable package) or a bug in synaptic?

[Daniel Cordeiro (dcordeiro)]

Also, the message in the output of the unicode program seems like an error and should not appear if the lack of UnicodeData.txt file is not mandatory. The previous versions of unicode didn't have this behaviour.

I am not an Ubunut developer, so hopefully somebody will take notice soon, but:

RE#4: I used packages.ubuntu.com to search for UnicodeData.txt and saw that it was in unicode-data and installed it before I noticed it was a suggestion. I did it all from command line, sorry.

RE#5: While it doesn't seem required it does get some extra info from it (silly emoji):

It may be a problem with the package description. When running:

$ LC_ALL=C apt-get --install-suggests -s --reinstall install unicode
NOTE: This is only a simulation!
      apt-get needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

apt-get did not attempt to install unicode-data (it is not currently installed).

[Sven Heinicke (svenmh)]

I would say just do:

sudo apt-get install unicode-data

to get rid of the unicode warning. If there is apt-get issue that is outside the scope of this bug. Never used it, maybe I'll start trying.

[Ian Turner (vectro)]

Seems pretty clear that if the unicode-data package is now required to use the unicode package (as seems to be the case), then the relationship should be Depends, not Suggests.
