I emphasized 3 characters.
These characters looks clearly different.

attached branch will fix this issue.
but I don't know whether it's right approach.

Arne,
You made this bug as a duplicate of bug #569442.
The fix of bug #569442 (* update fontconfig/69-language-selector-ja-jp.conf: change binding to 'strong') does not fix this issue.
So this is not a duplicate, I think.

Murata-san,

how does the output of
ls /etc/fonts/conf.d/
look like?

Cheers

attached "ls /etc/fonts/conf.d/ > output_etc_fonts_confd.txt" result.

[Arne Goetje (arnegoetje)]

ok, looks good. can you please attach your /etc/fonts/conf.d/69-language-selector-ja-jp.conf ?

[Nobuto Murata (nobuto)]

attached my /etc/fonts/conf.d/69-language-selector-ja-jp.conf.
It seems the same as the version 0.6.0 on Maverick.

Ah, I see the problem...

Looking at the source of the wiki.ubuntu.com page, it reveals, that the body text is tagged with lang=en and not lang=ja.
So, the real bug is that the wiki page does not use the correct language tag. Fontconfig is not to blame here.

Now the question is (and this needs to be discussed with the community), how to handle such cases.
The fontconfig way, to filter by language tag, does not work with such webpages. Removing the language tag filter, like the proposed patch does it, would mean, that the current fontconfig-voodoo hack would be needed forever and that there is no way to get a generic fontconfig configuration that works for everyone.

The proper fix (IMHO) would be to ask the sysadmins to make wiki.ubuntu.com support all available languages, so that we can use tags like '##language:ja' (old) or '#language ja' (new) in the wiki page to indicate that it should be rendered differently.
