Count the letters used in a sentence, by code point, generating a hash or associative array, or appropriate construct for the language.
Use the following. The Greek letters are random and don't spell anything that I know of.

ασδ ξκλ ασδ ξα
langur
<lang langur>var .countLetters = f(.s) {
for[=h{}] .s2 in split(replace(.s, RE/\P{L}/)) {
_for[.s2; 0] += 1
}
}
writeln .countLetters("fuzzy furry kittens") writeln .countLetters("ασδ ξκλ ασδ ξα") # random Greek letters</lang>
<lang langur>var .countLetters = f(.s) {
foldfrom(
f(var .h2, .s2) { .h2[.s2; 0] += 1; .h2 },
h{},
split(replace(.s, RE/\P{L}/)),
)
}</lang>
