I am using 10.7.1918, and I just found a bug when I am trying to rename a function with some Asian (Chinese/Japanese) characters before it in the same line. It will trigger "Visual Assist X failed to modify one or more files. The refactoring may not have completed successfully."
However, if I move the function to the second line, it works fine.
[rename is NOT working] cout << "#20013;#25991;: " << s.getStr();
