Package: diffoscope Version: 177 Severity: wishlist diffoscope currently prints a hex dump when comparing a TTF font with a .ttx XML dump of a TTF font. If it used ttx (from fonttools) to convert that TTF font to .ttx instead, then the comparison would become an XML diff, which diffoscope treats as a text diff, which is better than hex.
