(UTF8 Str in Material Name)Wings3 crashed when material name contain UTF8 string

[tkbd]

I have been continue validating and testing for case that include the UTF8 string in Wings3D data names.
Error occurs in three situations in relation to UTF 8 string.

• When set a UTF8 name for new Material.
  
• When Material rename to a UTF8 name.
  
• When AutoUV automatically generate material name from Object name that contain UTF8 code.
  

When Rename a Material

When set an UTF8 name with make a new Material.

When generate material(contain UTF8 name) name from UTF8 named Object UV.
The codes 95,97,117 and 118 mean "_auv" part of material name.

Code:

Using GPU shaders.
