You can easily test the language coverage of a font file using the

FC_DEBUG=256 fc-query <filename>

It will print all sorts of information, including a list of ISO 639
language codes followed by the number of associated missing codepoints
in the font file. For example:

aa(10) ab(90) af(17) ak(21) am(264) an(14) ar(36) as(64) ast(14) av(67) 
ay(8) { 00c4 00cf 00d1 00dc 00e4 00ef 00f1 00fc }
        az-az(14) az-ir(40) ba(82) be(68) ber-dz(18) ber-ma(32) bg(60) 
de(7) { 00c4 00d6 00dc 00df 00e4 00f6 00fc }
        dv(49) dz(95) ee(47) el(0) en(20) eo(12) es(14) et(12)

If the number is zero (el(0)) the font file contains all the bits needed
to write the associated language (Greek, not surprizing since Modata is
a Greek font), if it is non-zero it is missing this number of
codepoints, if it is non-zero and less than ten fc-query will print the
list of missing codepoints after the language number :
ay(8) { 00c4 00cf 00d1 00dc 00e4 00ef 00f1 00fc }

Of course just because a font includes support for lots of codepoints
does not mean they are all well designed. So it's just a minimal test.

Also don't test just the Normal font, the coverage of Bold/Italic/etc
can ans is often different.

As for Modata, ga(28) means it sucks for Gaelic (Irish)
