Bug Description

I asked support question 287448 about this issue and Actionparsnip suggested I file a bug about it.

I am running Ubuntu 15.10 with daily updates. When the title of a window contains non-ASCII characters they often (not always) are displayed as "replacement characters" (question mark in diamond, �). I can reproduce this with Firefox, Mozilla Thunderbird, and LibreOffice. By going to a directory with a non-ASCII sign in its name I can also reproduce it in gnome-terminal.

When I override Compiz (0.9.12.2) with Metacity the characters are displayed correctly.

I see no exact pattern in the affected texts; for instance, the titles of these two URLs both contain an "ö" (U+00F6) but only the first one exhibits the behavior in Firefox, the second displays the "ö" correctly:
* https://hu.wikipedia.org/wiki/S%C3%B6r
* https://de.wikipedia.org/wiki/S%C3%B6ldner

When I run compiz in a terminal I see the following messages when the problem occurs:
* unityreak_table (break_type) <unknown>:0 Invalid UTF-8 string passed to pango_layout_set_text()
* unity.windowmanager.x XWindowManager.cpp:107 Impossible to get the property WM_NAMEfor window ... properly: impossible to convert to current locale

My locale ($LANG) is eo.utf8, so there should not be a problem converting any Unicode string.

affects: software-center (Ubuntu) → compiz (Ubuntu)
