[jira] Commented: (XERCESC-1660) IconvGNU and IconvFBSD transcoders

[ http://issues.apache.org/jira/browse/XERCESC-1660?page=comments#action_12461505 ]
Alberto Massari commented on XERCESC-1660:
------------------------------------------
Hi Boris,
as you are contributing several bug fixes and patches, would you mind filing a corporate CLA as stated in the section 7 of the Xerces Charter at http://xerces.apache.org/charter.html? That would make easier for us to commit your patches.
Thanks,
Alberto

> When IconvGNU and IconvFBSD transcoders try to figure out the local code page, they call setlocale with an empty string as a second argument. This results in an implementation-specific action which usually consist of querying a set of environment variables and overriding the current locale with the result. This is obviously wrong since Xerces-C++ has no business changing the default application locale. Out of curiosity I checked how things are done in ICU. I found the following comment in the the source code:
> "Do not call setlocale(LC_*, "")! Using an empty string instead of NULL, will modify the libc behavior."
> I came up with a patch that addresses this issue as well as makes the detection code more robust.
