Sólo 01:01 asignación de caracteres se puede realizar por esta función, por ejemplo, la letra mayúscula griega "Σ" tiene dos formas minúsculas, dependiendo de la posición en una palabra: 'σ' y 'ς'. Una llamada a std::tolower no se puede utilizar para obtener la forma correcta minúsculas en este caso .

Original:

Only 1:1 character mapping can be performed by this function, e.g. the Greek uppercase letter 'Σ' has two lowercase forms, depending on the position in a word: 'σ' and 'ς'. A call to std::tolower cannot be used to obtain the correct lowercase form in this case.
