Where are you reading the string from? Do you know what encoding is used for the string? Strings in .NET is Uncocde, which supports virtually every character on the planet. (Characters that are not supported (yet?) are stuff like the Klingon alphabet and Tolkien runes...) Strings are usually not stored as 16 bit Uncode, so some kind of encoding is used when they are stored. You have to know this encoding to be able to correctly decode the string into Unicode. Some common encodings are 8 bit Unicode (UTF8) and Latin 1. ASCII encoding only support characters 0-127, so that is not suitable for what you are doing. --- b { font-weight: normal; }
