How to detect non-latin letters?
I'm making application which should be able to take string input from user (via input fields etc.) Important feature is that text MUST be only in Latin letters. How can I detect non-latin letters so that I could notify users about such input details.
Best Answer
//char can be casted to int to acquire letter's code
//returns true if letters are latin
bool CheckForNotLatin(string stringToCheck)
{
bool boolToReturn = false;
foreach (char c in stringToCheck)
{
int code = (int)c;
// for lower and upper cases respectively
if ((code > 96 && code < 123) || (code > 64 && code < 91))
boolToReturn = true;
// visit http://www.dotnetperls.com/ascii-table for more codes
}
return boolToReturn;
}
