Let me know if there's any reason this didn't make it in.
Of course, I will do my best to fix any problems.

- implement _ismbcalpha, _ismbcalnum

"War is an ugly thing, but not the ugliest of things;
the decayed and degraded state of moral and patriotic
feeling which thinks that nothing is worth war is much
worse. A man who has nothing for which he is willing
to fight; nothing he cares about more than his own
personal safety; is a miserable creature who has no
chance of being free, unless made and kept so by the
exertions of better persons than himself."

-- John Stuart Mill
