title: C++ How to check if letter isalpha (not latin alphabet)
body: <p>so I need to see if my character is a letter. I tried using isalpha() function, however, if I try to pass not latin letter (for example ą, č, ę, ė, į, š, ų, ū, ž) I get an error, that seems to state that isalpha function accepts only chars that in ASCII code are between 0 and 255. Is there any way to overcome this problem? </p>
