Package: libpango1.0-0 Version: 1.16.5-1 Severity: normal After upgrading my system, the latest Pango renders U+200B (zero-width space) visibly under certain conditions, as a "missing glyph" box containing the hex value. Particularly, Pango seems to be a looking for a glyph for this character matching the current language/script. In my case, Tibetan characters adjacent to U+200B cause the misrendering to happen.
I first observed the problem on a Google search (in Iceweasel) but have since been able to reproduce it in GTK+ text widgets by first typing U+200B (using an input method) then moving the cursor before the U+200B character and typing any Tibetan character. Thus, I am fairly confident that the bug is in Pango itself and not GTK+ or Iceweasel. I suspect the Tibetan fonts I am using lack a glyph for U+200B, but Pango should not be insisting on trying to find a "Tibetan version" of this character. It probably shouldn't even look for glyphs at all, but instead always treat it as a zero-width character with no visible glyph... but if it is going to use a glyph it should grab one from any available font.
