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....)
Anyhow，我剛寄了個 bug report 給 bsdmainutils 的維護者，希望他
在下一版予以修正。您心急的話，可以自行 "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! 移除中文化路途上的一個絆腳石……
