My bad.

I was running 1.9.1, which had no FIXEDENCODING.

Regexp.constants
=> [:IGNORECASE, :EXTENDED, :MULTILINE, :ONCE, :ENC_NONE, :ENC_EUC, :ENC
_SJIS, :ENC_UTF8]

So things have changed since 1.9.1

If you are running 1.9.2 then use FIXEDENCODING and you should be fine.

I THINK that you are saying with FIXEDENCODING is NOT to revert back to
something like ASCII.

BTW in 1.9.1

>> Regexp::ENC_EUC
=> 16
>> Regexp::ENC_SJIS
=> 16
>> Regexp::ENC_UTF8
=> 16
