Allow non-English words in identifiers

[kerrykimbrough]

It should be possible to use non-English words as identifiers in all components of a SystemInputDef

For Tcases, an "identifier" is intended to be a sequence of one or more words or numbers, separated by either hyphen or underscore. Currently defined by the regex [A-Za-z0-9_-]+. I'm thinking of changing this to [\p{isAlphabetic}\p{isDigit}_-]+. But I'm not sure how well this works for Japanese and Chinese character sets. @tkruse, any advice?

Though for System name and function name, maybe the concept of a name is different from that of an identifier. What makes an identifier special to me is that it can be evaluated in expressions (such as boolean expressions or method invocations etc.). For properties and even variable names, it seems acceptable that they might need to be processed in other larger expressions. So they need identifiers not just names.
