Description

Hi,

There is an issue matching a string like "a *b* c *d*<" when the encoding of the file is set to UTF-8 and the regexp is attempting to match '*something*'. Afaik, *< is not special in the encoding.

This gist illustrates the issue:

Thanks,

'<' is not Punctuation on Unicode; it is Math_Symbol.
