Hum, yes, let's fix this. But honnestly, we use the is* functions for parsing and checking input, and one thing I worry about is having a behaviour different based on the user locale. For example I see we now use isupper/islower/isspace which are locale dependant, they seems to be confined to places which are not raw user input, but we should keep an eye to avoid problems.
