Package: fontconfig Version: 2.11.0-1 Severity: important Dear Maintainer,
The problem started to occur after the latest upgrade to fontconfig, and originated as a powerline bug report <https://github.com/Lokaltog/powerline/issues/701#issuecomment-28484432>. Here is some background information. - Powerline uses a private unicode block for custom symbols; it thus provides a custom otf font (see <https://powerline.readthedocs.org/en/latest/installation/linux.html> for details) that provides five glyphs or so. The font is called powerlinesymbols and does *not* provide any glyph for the space 0x20 and non-breaking space 0x0a charaters. - The Powerline setup implies putting this in your local font config : <alias> <family>Monaco</family> <prefer><family>PowerlineSymbols</family></prefer> </alias> (I'm using Monaco as an example). That way, the symbols are first picked up in the custom block provided by PowerlineSymbols, and then in Monaco. Until the recent upgrade to fontconfig, this worked just fine. Now, *some* space characters are displayed using the "default glyph", the one that shows a block with the hex letters. The original bug report on GitHub contains some screenshots. I'm really puzzled, and I still suspect this is somehow linked to fontconfig : indeed, the problem started happening after the fontconfig update, and if I remove the <prefer> directive from my local configuration, the spaces are displayed properly (but the custom symbols aren't, of course). It may be that the bug lies elsewhere. However, I'm not an expert enough on font issues to debug this any further. I'd love it if you could at least tell me that this is a bug in fontconfig, or not!
