[EMAIL PROTECTED]@找到原因了。 /usr/bin/write 是非常之非常之非常之非常之不 
8-bit clean。
可惡，竟然濾掉所有 8-bit 至 7-bit。想不到現在還有那麼多程式不 8-bit clean。
（竟然用 toascii()……太過份了！）  ^_^  toascii 的 man page 說得是：

       Many  people  will  be  unhappy  if you use this function.
       This function will convert accented  letters  into  random
       characters.

(You guessed it... I am more than unhappy!  grrrrr....)

[EMAIL PROTECTED]@Anyhow，我剛寄了個 bug report 給 bsdmainutils [EMAIL 
PROTECTED]
[EMAIL PROTECTED] "apt-get source bsdmainutils"
（要 potato/woody 裏 version 4.8 那個），
再加以下的 patch，所來個 "make write"，就可以了。  ^_^  Thanks for
reporting this problem!  [EMAIL PROTECTED]
