usage: gftools-fix-isfixedpitch [-h] --fonts FONTS [FONTS ...]

It is important for monospaced fonts to have the 'isFixedPitch' flag set to 1 in the post table.
If it is set to 0, Windows coding programs categorize them as proportional fonts, and they will
not appear as options in font selection preferences. This script checks whether a font or
collection of fonts appears to be monospaced by checking for equal widths in the entire Latin
lowercase, a to z. If these are equal, 'isFixedPitch' will be set to 1. If a-z are unequal,
'isFixedPitch' will be set to 0. Usage: gftools-fix-isfixedpitch --fonts [font1.ttf font2.ttf ...]
