[fixed] OSX,Wings2.0.2, CJK Language, Crashed when openig Plug-In-Manager

[tkbd]

By following bug, can't use Plug-in-Manager in these languages.

How to make this problem.

1. In Wings3D's pereference dialog ,swith to Chinese or Japanese.
2. (For example Japanese version)Select "編集>プラグイン管理" for open Plug-In-Manager.
   This command means that same operation selection "Edit＞Plug In Manager" in English UeseInterface.
3. Then Wings3D crash.( this occurs also in v1.5.4 .)
   

The cause is ....

A problem occurs when probably the Plugin Manager to get the information of the three plug-ins
wpc_circularize
wpc_frow Connect
wpc_inset

If remove these module files, Plugin manager doesn't crash.
Other commands no problem for display also contain CJK characters in menu entry.

For example a crash log which case circularize.

These are Japanse translation string of "Circularise" for menu entry string.
