#1 "unknown escape sequence" warning when compile with TChinese

[Yu-Wei Chang]

Because some characters like "許" (0xB35C), "功"
(0xA55C), "蓋" (0xBB5C) in Big5 characterset use
character '\' (0x5C) in its lower byte.

This problem will cause the "unknown escape sequence"
warning when compile with the TChinese.h file.

One of the solution is adding an additional character
'\' (0x5C) after these kind of big5 characters to
escape their lower byte like "許\" (0xB35C5C)
