When using the "P4 Plugin" against our Unicode enabled Perforce server to checkout our project files, the byte order mark on some utf-8 files is doubled up.

Example: 

0xEF,0xBB,0xBF,0xEF,0xBB,0xBF,....

instead of

0xEF,0xBB,0xBF,....

We attempted to retrieve the same files using the P4V client and this duplication of the byte order mark did not occur. Both the "P4 Plugin" and "P4V client" are configured to use CHARSET=utf8.

Any help in fixing this issue would be greatly appreciated. We are trying to get our build system working and can't get past the build step because our Visual Studio project files are corrupted by this duplication of the byte order mark.
