11.12 BUGS

There are numerous problems with case insensitive matching of characters outside the ASCII range, especially with those whose folds are multiple characters, such as ligatures like LATIN SMALL LIGATURE FF.

In a bracketed character class with case insensitive matching, ranges only work for ASCII characters. For example, m/[\N{CYRILLIC CAPITAL LETTER A}-\N{CYRILLIC CAPITAL LETTER YA}]/i doesn't match all the Russian upper and lower case letters.

Many regular expression constructs don't work on EBCDIC platforms.

This document varies from difficult to understand to completely and utterly opaque. The wandering prose riddled with jargon is hard to fathom in several places.

This document needs a rewrite that separates the tutorial content from the reference content.
