Ok, here are some rules to verify EUC_TW characters:

(1) if the first byte is 0x8e, then the 8th bit of following three
    bytes must be set

(2) else if the first byte is 0x8f, then the 8th bit of following two
    bytes must be set

(3) else if the 8th bit of the first byte is set, then the 8th bit of
    following one bytes must be set

(4) else (that means the 8th bit of the first byte is not set) then
    that must be an ASCII character.

Apparently 0xa672 does not satisfy all of above.
