when i input '\n', '\x000A' or '\u000A' in Qt Linguist, it appears as string(for example, "My name is \n Hong"), not control character.
how can i input control characters in Qt Linguist?
Just press the return key, linguist inserts the newline automatically. For other unicode characters: Just type them. The .ts file is UTF-8 XML - you do not need to enter that special chars in C/C++ escaping mode.
