There's no spacing attribute in TrueType fonts, so that is contingent
upon how the MS Windows font scaler detects fixed pitch fonts. Here's
how ftfont.c calculates the average width for fonts that Fontconfig
deems fixed pitch:
font->min_width = font->average_width = font->space_width
= (scalable ? ft_face->max_advance_width * size / upEM + 0.5
: ft_face->size->metrics.max_advance >> 6);
That aside, Fontconfig does not judge Noto Sans Mono CJK JP a fixed
pitch font on my system.
