Look at the Character Map (Start..run... type "charmap").
Select your desired font, select "advanced view" and select a windows character set, e.g. "Windows: Western" (AFAIK, LabVIEW does not support unicode, a 16 bit/character encoding standard). Click on any charcacter and you'll see the corresponding hex code. For example, the Arial copyright symbol (©) would be 0xA9 or \A9 in "'\' Codes".
