[why] Some glyphs are just used as overlays for 'real' glyphs. These can be for example U+0300 .. U+036F (the 'COMBINING ...' diactritics) like U+0300, gravecomb, COMBINING GRAVE ACCENT U+0301, acutecomb, COMBINING ACUTE ACCENT U+0308, uni0308, COMBINING DIAERESIS They are never used on their own, at least they are overlayed over a blanc (U+0020, space). For the font rendering engine they need to have the correct negative bearings, so they are shifted to take no space by themselves. The font-patcher script does not allow negative bearings in monospaced fonts. This makes sense if every glyph is in itself a 'letter' that should not reach beyond it's allotted (monospaced) space. [how] In the font-patcher script we do not touch the bearings of such overlay glyphs. They can be identified by their width of zero. For Windows to detect this font as 'monospaced' we need to change the width to the standard width, though. Signed-off-by: Fini Jastrow <ulf.fini.jastrow@desy.de>
