"Reading" message charset

[jidanni@xxxxxxxxxxx]

I enter
URL or Keyword (default HOME): http://www.google.com.tw/search?q=台中縣+戶政課
and there is a brief message in the middle of the screen that it is
"Reading" that URL.

However the character set for this brief message looks like it is
still iso-8859-1, even though I do (setq w3m-default-coding-system
'utf-8).

Also that brief message is gone with no way for me to find it and show
it to you. It is not stored anywhere.
