Incorrect test inputs produced for RegEx word character

See original GitHub issue

Specifying a pattern using a word character (e.g. ^[\w\-.~]+$) causes invalid generated test inputs such as ŏŏşNÇţā3MKÁŔßïõŜàĆXń²ńÖÞ.

Replacing the above RegEx with ^[A-Za-z0-9_\-.~]+$ fixes this issue, so I assume that CFN CLI has a bug specifically related to \w.

I may also argue that according to JSON Schema docs we shouldn’t be allowing regex patterns that use \w

According to ECMA 262,

\w, \W, \b, \B, \d, \D, \s and \S flags in regex should be ASCII based not unicode
Unicode is the default in python so we should switch to ASCII (minus the service flipping with a flag)

More details: https://docs.python.org/3/library/re.html#re.ASCII https://262.ecma-international.org/5.1/#sec-15.10.2.12 http://json-schema.org/understanding-json-schema/reference/regular_expressions.html
