[QUOTE="arion_p, post: 161670, member: 45945"] Hi james, I tried your code this morning but it didn't work. I also remember reading some article about Greek Final Sigma special casing rules in Unicode. According to the article the special casing rules where initialy included in the Unicode draft but later on they where dropped to avoid complexity. However the current version of Unicode includes those rules. Anyway it seems the NET team decided not to implement those rules (regardless of Unicode standards). Actually, I think the problem is not with ToTitleCase() but ToLower(). ToTitleCase() takes a lower case string and uppercases the first letter of each word. If you pass an upper case string it returns it unchanged. In WebEPG, when a title with upper case only letters is found it is first turned to lower case via ToLower() and then the result is fed to ToTitleCase(). It is ToLower that fails to properly lower case Greek Sigmas. E.g. (hope you can see Greek characters) "ΙΣΩΣ" should become "ισως" but ToLower() returns "ισωσ" ("Σ" becomes "σ" in the middle of a word but "ς" at the end) Along the above notes I have also tried the following code (that didn't work either): [CODE] CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture; TextInfo textInfo = cultureInfo.TextInfo; string titlecase = textInfo.ToTitleCase(textInfo.ToLower(uppercase));[/CODE] I also tried specific Culture (both "el" and 1032) and InvariantCulture (shouldn't work anyway) The only way I could make it work is using RegEx: [CODE] CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture; TextInfo textInfo = cultureInfo.TextInfo; Regex re = new Regex("\\u03c3(?=($|\\W))"); string titlecase = textInfo.ToTitleCase(re.Replace(textInfo.ToLower(uppercase), "\u03c2"));[/CODE] Thanks, Panayotis [/QUOTE]
