recode converts cp1252 code point incorrectly
Last modified: 2009-07-14 14:14:48 EDT
Description of problem:
GNU recode does not convert cp1252 code point 0x9E to UTF-8.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. echo -n $'\x9E' | recode -s cp1252..utf8
recode: Ambiguous output in step `CR-LF..data'
ž (UTF-8 encoding of U+017E LATIN SMALL LETTER Z WITH CARON)
All other cp1252 code points are recoded correctly.
The command "echo -n $'\x9E' | recode -s cp1252..utf8" gives
"recode: Non canonical input in step `CR-LF..data'" for me on Fedora 9.
Oops. Cut-n-paste error: omitting "-s" gives the error I submitted. Either way it's still a bug.
According to the character tables of recode (as shown by 'recode -l
cp1252'), character 0x9e does not exist. It seems the table is incomplete.
I'm trying to contact the upstream maintainers.
(In reply to comment #3)
Notice that the code point appears (incorrectly) at position 0x8F despite the code in libiconv/cp1252.h seeming to have the code point in the correct position. GNU Recode does not do the round-trip conversion however:
$ echo -n $'\x8F' | recode -s cp1252..utf8
ž (wrong but at least it matches "recode -l" output).
$ echo -n ž | recode -s utf8..cp1252 | hexdump -C
00000000 9e (correct but inconsistent)
GNU Recode has not been updated in a long time. Not surprising since glibc provides iconv. Maybe it would be better for packages to stop using recode?
Created attachment 320026 [details]
Correct position of CP1252 code point 0x9E.
I've attached a patch which corrects the recoding error. However, it modifies a generated file and I don't have time at present to generate a proper patch. Still, I hope this helps.
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '9'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 9's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 9 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
Problem still exists in Fedora 11.
