Erlang - Eccentricity with accented characters and string literal
- by erevfall
Hey,
I am trying to implement a function to differentiate between french vowels and consonnants. It should be trivial, let's see what I wrote down :
-define(vowels,"aeiouyàâéèêëôù").
is_vowel(Char) -> C = string:to_lower(Char),
lists:member(C,?vowels).
It's pretty simple, but it behaves incorrectly :
2> char:is_vowel($â).
false
While the interpreted version works well :
3> C = string:to_lower($â), lists:member(C,"aeiouyàâéèêëôù").
true
What's going on ?
