[PATCH v5 0/7] convert: add support for different encodings

From: Torsten Bögershausen <tboegi@web.de>

Take V4 from Lars, manually integrated the V2 squash patch, so a review would be good.

Add my "comments" as a patch, see 7/7 (and this is more like an RFC)

This needs to go on top of tb/crlf-conv-flags

Lars Schneider (6):
  strbuf: remove unnecessary NUL assignment in xstrdup_tolower()
  strbuf: add xstrdup_toupper()
  utf8: add function to detect prohibited UTF-16/32 BOM
  utf8: add function to detect a missing UTF-16/32 BOM
  convert: add 'working-tree-encoding' attribute
  convert: add tracing for 'working-tree-encoding' attribute

Torsten Bögershausen (1):
  Careful with CRLF when using e.g. UTF-16 for working-tree-encoding
