ansi characters:
===============
1st character: 75 NG, 53 OK ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz
</pre>▼
2nd..nth char: 65 NG, 63 OK 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz
utf8 characters:
===============
good:48, bad:1111888
, Έ, Δ, Κ, Σ, λ, π, ψ, ϔ, Ϛ, ϣ, ϻ, , , —, ‚, ‣, ※, ∀, ∈, ∔, √, ∣, ∻, ─, ┈, └, ┚, ┣, ┻, ⚀, ⚈, ⚔, ⚚, ⚣, ⚻, ⣀, ⣈, ⣔, ⣚, ⣣, ⣻, ⻀, ⻈, ⻔, ⻚, ⻣, ,
▲</pre>
Note that ptok.e (part of the compiler) currently contains the following:
<lang Phix>charset[#80] = LETTER -- more unicode
Line 415 ⟶ 458:
charset[#CF] = LETTER
charset[#E2] = LETTER</lang>
If that is extended (with more utf-8 handling) then obviously the output will change.<br>
I am a little surprised at just how few ad-hoc utf8 characters have been supported so far.
