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,

And redcloth3's exapmle is a bug, they should use their PUNCT constant.
