titleize missing in ActiveSupport::Multibyte::Chars

That's correct, none of the inflection methods are multibyte safe. Inflection methods were primarily written to juggle table and constant names and are used quite a lot in core code. I'm afraid Rails would slow down a lot if we would make them multibyte safe.

However, I wouldn't mind accepting a patch with a ActiveSupport::Multibyte::Inflections module which can be included into Chars to add these methods.

The attached patch resolves the reported issue.

Rather than create an Inflector module, however, I just added a #titleize method to Multibyte::Chars.

This was for two reasons. One, there was already a capitalize method there, and this is conceptually similar.

Two, none of the other methods in Inflector seem particularly useful in a multibyte context: what's the point of a separate classify or underscore method, when you can just do something like:

Inflector.transliterate(string).tableize

if you really need to get a table name from a string with multibyte chars. If we provide a method for this, it's not entirely clear to me how we should handle non-Roman strings that can't easily be approximated to ASCII, since for example, Ruby doesn't allow UTF-8 characters in constants. Also, pluralizing non-English strings will generally just lead to hilarity:

"Männer".mb_chars.tableize # => "manners"

That looks completely absurd to a German speaker. :-)
