Right, the default behaviour of trim() is *known* to be multibyte safe.

What SSH client do you usually use? I use TeraTerm Pro with an SSH 
extension.

TeraTerm Pro: http://hp.vector.co.jp/authors/VA002416/teraterm.html
TTSSH: http://www.zip.com.au/~roca/ttssh.html

Yes, there could well be the wonderful mb_trim() and your contribution 
will be greatly appreciated, but I don't realise the number of people who 
demand that yet, and some equivalent made of userland functions will 
suffice. Your request still seems to me in a narrow niche :)
