utf8Strup

fnstring utf8Strup(string str)

Converts all Unicode characters in the string that have a case to uppercase. The exact manner that this is done depends on the current locale, and may result in the number of characters in the string increasing. (For instance, the German ess-zet will be changed to SS.)

Parameters

stra UTF-8 encoded string

Returns

a newly allocated string, with all characters

converted to uppercase.
