Attaching the patch.
> IconvGNU and IconvFBSD transcoders override application-set locale
> ------------------------------------------------------------------
>
> Key: XERCESC-1660
> URL: http://issues.apache.org/jira/browse/XERCESC-1660
> Project: Xerces-C++
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 2.7.0
> Environment: any
> Reporter: Boris Kolpackov
> Attachments: setlocale.patch
>
>
> 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.
