YamlParser.ReadScalarAsString lockup when encountering some rare unicode characters

[Amethyst-szs]

Problem:

Been working on parsing a large database of text in different languages and ran into a set of Unicode characters that causes YamlParser.ReadScalarAsString to lock-up permanently without an throwing an exception or any other form of error.

Example:

The initial culprit was "２", the full-width two character [U+FF12]. Some surface level testing showed that the other full-width numbers cause the same parsing lockup issue. All other text I tried supplying ran without issue.

Priority

This isn't a super high priority fix for me, I can just clean up the data before passing into the YamlParser, but thought it was worth documenting in case this is a sign of a larger unicode handling issue? Thanks, take care!
