[PATCH v2 0/3] MR7777: conhost: Improve first font selection on systems with limited fonts.
-- v2: conhost: Imrove best matching font selection in set_first_font. conhost: Merge validate_font and validate_font_metric helpers. conhost: Allow raster fonts in enum_first_font_proc.

Otherwise, on systems with only Wine provided fonts, we end up selecting first non-vertical font ignoring other properties. --- programs/conhost/window.c | 98 ++++++++++++++++----------------------- 1 file changed, 39 insertions(+), 59 deletions(-)

Sure, I can enable raster fonts instead of dropping all code related to it. How is the last patch changing weights of the criteria? The code was already preferring fixed fonts over charset. Giving weight to charset (as oppossed to completely ignoring it if there's no fixed width font) is already fixing the issue. While it might make sense to improve weight calculation there's probably little benefit doing so (most systems will have a font that matches all criteria anyway).
I have pushed a version that allows raster font to be selected. Other code is not changed since I don't think there's anything wrong with weight computation (comparing to old behavior).

I'd rather pick a non fixed font with correct charset over of fixed font with a non matching charset (agreeing that that case didn't exist in current code, and is potentially pedantic)
