So what you are telling me is that there is not a way to use the Regex tools in .net to match on chars outside of the utf-16 range?

The full regex is:

^(\u0009|[\u0020-\u007E]|\u0085|[\u00A0-\uD7FF]|[\uE000-\uFFFD]|[\U00010000-\U0010FFFF])+$

I am attempting to check if a string only contains what a yaml document defines as printable Unicode chararters.
