Test character encoding

  $ hg init t
  $ cd t

we need a repo with some legacy latin-1 changesets

  $ hg unbundle $TESTDIR/legacy-encoding.hg
  adding changesets
  adding manifests
  adding file changes
  added 2 changesets with 2 changes to 1 files
  (run 'hg update' to get a working copy)
  $ hg co
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ python << EOF
  > f = file('latin-1', 'w'); f.write("latin-1 e' encoded: \xe9"); f.close()
  > f = file('utf-8', 'w'); f.write("utf-8 e' encoded: \xc3\xa9"); f.close()
  > f = file('latin-1-tag', 'w'); f.write("\xe9"); f.close()
  > EOF

should fail with encoding error

  $ echo "plain old ascii" > a
  $ hg st
  M a
  ? latin-1
  ? latin-1-tag
  ? utf-8
  $ HGENCODING=ascii hg ci -l latin-1
  transaction abort!
  rollback completed
  abort: decoding near ' encoded: é': 'ascii' codec can't decode byte 0xe9 in position 20: ordinal not in range(128)!

these should work

  $ echo "latin-1" > a
  $ HGENCODING=latin-1 hg ci -l latin-1
  $ echo "utf-8" > a
  $ HGENCODING=utf-8 hg ci -l utf-8
  $ HGENCODING=latin-1 hg tag `cat latin-1-tag`
  $ HGENCODING=latin-1 hg branch `cat latin-1-tag`
  marked working directory as branch é
  $ HGENCODING=latin-1 hg ci -m 'latin1 branch'
  $ rm .hg/branch
