expansion fails upon pipes in big5 chars

[Dan Jacobson]

$ echo 05017法規修訂座*
05017法規修訂座談會-1.pdf  05017法規修訂座談會.pdf
hitting tab gets caught in the hidden "|" in the last byte:
$ echo 05017法規修訂座談愧|
Display all 3261 possibilities? (y or n)

Therefore bash filename expansion fails upon pipes in big5 chars
$ echo 會|qp-encode
=B7|
It knows it is one char though:
$ echo 05017法規修訂座談?.pdf
