“Make Accel Key” feature on a DBCS (double-byte characters) string (such as: Chinese) is not valid.

Following is a description in the Microsoft Localization Studio:
1. DBCS style hotkeys must always appear at the end of the base string, surrounded by parentheses. The hotkey must be the same as the source, but in uppercase, surrounded with parentheses, and placed at the end of the string before any terminators. Example: "&File..." should be translated as "File(&F)...".
2. DBCS hotkey characters must be the same as the (uppercase) source term. Examples: &File... -> File(&F)..., Cu&t...\tCtrl+X -> Cut(&T)...\tCtrl+X
3. DBCS hotkeys should appear at the end of the base string, e.g., File(&F)
4. DBCS hotkey characters should be the same as the (upper-cased) source.

We will fix this issue in the next releases.
