Description Stefan Behnel 2006-05-08 12:37:16 UTC 
Please describe the problem:
libxml2 fails to parse auto-detected UCS-4LE in-memory data (and likely others).
The reason is that it determines the encoding to be "UCS-4LE", then asks iconv
for "ISO-10646-UCS-4" (which iconv does not know) and then lets iconv find a
codec for "UCS-4", which is different from "UCS-4LE". Parsing as "UCS-4" fails.


Steps to reproduce:
1. parse a UCS-4LE buffer - fails
2. ask libxml2 to autodetect the encoding: XML_CHAR_ENCODING_UCS4LE
3. ask libxml2 what the name of the encoding is: "ISO-10646-UCS-4" (note the
missing "LE")

Parsing the buffer with an explicit encoding "UCS-4LE" works.

Actual results:


Expected results:


Does this happen every time?

Comment 1 GNOME Infrastructure Team 2021-07-05 13:26:36 UTC 
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/libxml2/-/issues/

Thank you for your understanding and your help.
