Question

How can I find out if a specific character in a QString is a letter or punctuation in any language?

For example I want to find the . in gâteau. but not the â.

In which language you are working? – Shaikh Farooque Apr 19 '12 at 15:45 — Shaikh Farooque, Apr 19 '12 at 15:45

Try

str.at(i).isLetter()

It will return true for the unicode classes Letter_Uppercase/Lowercase/Titlecase/Modifier/Other. Which you can see here:

You can get a QChar out of a QString using at(), and QChar has a isLetter() function. Thus, you want something like:

QString myString;
if (myString.at(3).isLetter()) {
   qDebug() << "letter number 4 in the string is a letter";
}
