Bug ID: 5590
Summary: Change in encoding is not detected as a change by
Mercurial
Product: Mercurial
Version: 4.2.1
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: bug
Priority: wish
Component: Mercurial
Assignee: bugzi...@mercurial-scm.org
Reporter: la...@lassekliemann.de
CC: mercurial-devel@mercurial-scm.org
The following script demonstrates the problem. A file 'f' is created with a
single umlaut, then converted from the default UTF-8 to ISO-8859-1 (this step
should not be important) and then added and committed. Then the encoding is
changed from ISO-8859-1 to MacCentralEurope. The file *is* different as proven
by a comparison with the backup copy 'g'. However, neither 'hg st' nor 'hg
diff' nor 'hg ci' recognize any change. This is creating severe problems here,
and any help is very much appreciated. Thanks!
As far as I understand, Mercurial does not care about the encoding of file
content but just treats the file 'as is'. So the change in encoding should be
recognized as a change in the file.
$ hg init test.hg
$ cd test.hg
$ echo 'รค' > f
$ recode UTF-8..ISO-8859-1 f
$ file f
f: ISO-8859 text
$ hg add f
$ hg ci -m na
$ hg st
$ cp f g
$ recode ISO-8859-1..MacCentralEurope f
$ file f
f: Non-ISO extended-ASCII text
$ hg st
? g
$ hg diff
$ hg ci
nothing changed
$ cmp f g
f g differ: byte 1, line 1
