Ruby 1.9 allows method names to include non-ASCII characters with the following caveats:

• The characters must be valid in the file's source encoding.

• A legal method name that does not end with '!', '?', or '=' may have one of these characters appended.

• The ASCII punctuation characters of which operator methods consist (e.g. {{{[*%&^`~+-/\[<>=]}}}) must not appear in any other permutation, with the exception of the above case.

Pygments does not recognise such method names, lexing the first non-ASCII character as an error. Examples of unrecognised method names are given in http://pygments.org/demo/3147/ .
