This is a good starting point for seeing where we are with Unicode support and 
where we need to go.

Possible, but don't do it :). The table would have like 0x18000 entries (just a guess). If each character name is 20 letter long, Phobos need to supply a 2 MB file for this rarely used feature. Besides, D has '\&afr;' already. There are more important features like Unicode properties, normalization (á <-> a´), locale-specific casing (dotless i), collation etc. that should be supported before having \N. (I'd prefer these be done via a wrapper to ICU, as most are database-based.)

Let me expand a bit my reply on bugzilla. There are other things I'd like to note, besides conforming to unicode regex standard, that is (going to be) fully supported in upcoming next-gen std.regex. Things I'd love to see in an upgrade of std.uni: - normalization (at least NFC) - unicode version 5.0 ---> 6.0 - grapheme support, via a special range on top of string or at least plain "stride" function that tells the length of a cluster a-la the one that does UTF-8 decoding I had to (re)implement a lot of stuff, with the end result that the unicode support in regex is self-contained right now. Of course, I'd be willing to make arrangements to gradually shift some of this stuff back where it belongs, once I'm finished with regexes. -- Dmitry Olshansky

Sounds great!
