 * milestone:  5.3 => Future Release


Comment:

 As far as I understand `remove_accents()` is meant to replace accented
 letters from Latin based languages with their non-accented equivalent (as
 much as possible) only for the
 [https://en.wikipedia.org/wiki/Unicode_block Latin-1 Supplement, Latin
 Extended-A, and Latin Extended-B] Unicode blocks.

 It is not meant to "reduce" a string containing chars from the above
 Unicode blocks to an "ASCII equivalent", however in practice this is often
 the case. Looking back, seems it was added to both sanitize and make
 permalinks and user names easy to url-encode and look better (SEO
 related?), although there may have been other reasons.

 Looking at the questions @xkon raises, `remove_accents()` would probably
 need better documentation, and in the longer run, a re-evaluation and
 refactoring.

 In that terms moving to "future release" for now. Please feel free to add
 back to 5.3 if feasible.
