The NLS catalog of csh(1) is not enabled on RELENG_6 and HEAD since
tcsh 6.14 was imported.
The tcsh 6.14 uses libiconv to convert catalogs to appropriate charset
dynamically. However, we don't have libiconv in our tree. So, I made
some hack to load libiconv dynamically.
With my patch applied, if libiconv is available, you can use catalogs
for more locales than the locales which catalog is actually installed.
To use this feature, you need to symlink catalogs to appropriate
locales. I made a port to do this.
You can get the patch and the port from:
