So ψ_S alone is fine, if everything else is Greek.
But mixing with the Cyrillic version would lead to an error.
Allowing mixing of Greek and Latin (or Cyrillic and Latin) would be a
big problem. As an example, it would allow A_Α (the second letter is a
Greek one).
Amharic is not defined as UCD script property. It’s alphabet is called Ge’ez,
which we call
Ethiopic in the UCD. But that’s all I know. I’m not a domain expert. Does
Ethiopic uses
other Semitic scripts in its alphabet or is it complete?
It's complete. I have never heard that it would need Arabic or Hebrew or
some such.
How about the many Indian scripts? Do they mix?
Being an indian movie expert tells me that indian languages usually don’t mix.
They make Tamil and Bengali versions of Hindi movies, and usually fall back to
english to
get common points across the barrier. But their scripts? No idea.
I don't think they mix two different scripts in the same word. Would be
very confusing.
In the examples in perl which partially came from parrot there’s a wild
eclectic mix of various scripts
which do make no sense at all. So I don’t know if I can trust those tests, that
they make sense and
are readable at all. My guess is that the authors just liked code golfing and
picked random unicode
characters. It’s from perl after all.
Such as this perl test t/mro/isa_c3_utf8.t
use utf8 qw( Hangul Cyrillic Ethiopic Canadian_Aboriginal Malayalam Hiragana );
...
package 캎oẃ;
package urḲḵｋ;
@urḲḵｋ::ISA = 'kഌoんḰ';
package к;
@urḲḵｋ::ISA = ('kഌoんḰ', '캎oẃ');
package ṭ화ckэ;
...
These identifiers are unreadable, because I don’t assume that anybody will be
able to understand
Hangul Cyrillic Ethiopic Canadian_Aboriginal Malayalam and Hiragana at once.
I understand a bit Hangul, Cyrillic and Hiragana, but the mix sounds highly
illegal to me.
The mixes aren't illegal, in that they are not against any law. But they
are complete intellegible garbage anyway.
