unicode_names2 vs unicode-segmentation vs unicode-width

Map characters to and from their name given in the Unicode standard. This goes to great lengths to be as efficient as possible in both time and space, with the full bidirectional tables weighing barely 500 KB but still offering O(1)* look-up in both directions. (*more precisely, O(length of name).)

This crate provides Grapheme Cluster, Word and Sentence boundaries according to Unicode Standard Annex #29 rules.

Determine displayed width of `char` and `str` types according to Unicode Standard Annex #11 rules.
