Yes, this has come up before.  OpenBSD's regexps, for some reason,
don't seem to allow characters above the ASCII range.  Possibly, this
is a locale issue.  Have you tried running with en_US.ISO8859-1 or
whatever the local equivalent is?

(I have no explanation why it didn't occur with 0.6.2, but that was a
long time ago.)
