How to determine if a CultureInfo instance supports Latin characters

Question

Is it possible to determine if the CultureInfo instance that I am working with is based on a Latin character set or not?

Answer 1

I believe you can use the CultureInfo.TextInfo.ANSICodePage. There are only so many of these (detailed here: http://msdn.microsoft.com/en-us/goglobal/bb964654).

You mostly just need to check that it's value is either 1252 or 1250

Answer 2

Not sure whether this is sufficient, but how about testing the CultureInfo.NativeName property for Latin characters using the CharUnicodeInfo.GetUnicodeCategory method
