locale aware versions of isAlpha(), toUpper(), isUpper()

[awaresoft]

I'm looking for a way to write locale aware Jscript string functions such as IsAlpha(), toUpper(), isUpper(), etc. so that my code can recognize letters unique to a user's country, ie. French, Spanish, German, letters with accents, etc.

Does anyone know of any library's, ActiveX, or other technique that will allow me to get access to the Windows API's that provide this type of information? I'm open to using VBScript if there's a way to get access to this info via VBScript.

I'm writing JScript code for IE 5.5 or higher.

Thanks!
