Yes

I switched sometime ago to 1.9 and my app now uses ordered hashes and
enumerators.

For the time being, it works with the strange ::Fixnum fix. I cross
fingers and shall try 1.9.2 later on, when officially released. But
1.9.2 implies (or is it 1.9.x ?) - alas poor Yorick! - changing
Regexp's : \d, \s,\w and the like work no more with utf-8 encodings!

Certainly there are cool new features in 1.9, and apparently improved
speed. But these are outweighed for me by the total mess which is
encodings.

Care to share an example, or point to a blog with more details? I have
an older 1.9.2 lying around, it doesn't seem to behave how you describe.

It was written in a post in this forum (or ruby core) I think from
Yusuke Endoh about the coming 1.9.2 release. You have to replace \d by
\p{Digit}, and similarly for \s, and the like... Sad perspective.

Look at the beautiful example !

RangeReg =
/\A(\p{Digit}+|\p{Digit}+\.\.\p{Digit}+)(,\p{Space}*(\p{Digit}+|\p{Digit}+\.\.\p{Digit}+))*\Z/

I think I'll add a Regexp#one_nine_two_escape method!
