According to the Unicode specification (at least as of 5.1), CRLF sequences are considered to be a single grapheme. We cater to that special case by letting grapheme_ascii_check() fail. While it would be trivial to fix grapheme_ascii_check() wrt. grapheme_strlen(), grapheme_substr() and grapheme_strrpos() would be much harder to handle, so we accept the slight performance penalty if CRLF is involved.
