It seems that WorldCat provider accepts book search by UTF-8
string.

With alexandria-0.6.5-7.fc12 book search by UTF-8 string on WorldCat
provider returns some results, however it does not detect the titles
of the found books correctly.

How to reproduce:
* Launch alexandria
* Make sure that WorldCat provider is selected at the top of the
  Providers' list
* Select "Add book" -> "Select by title", enter the string
  "ハヤテ" (Hiragana string, in Romaji "hayate")

Result:
The result of "$ alexandria --debug" is put on:
http://mtasaka.fedorapeople.org/Bugfix/alexandria-WorldCat-Hiragana.log

Some part of this log is as below:

A small correction

"ハヤテ" is actually Katakana, not Hiragana :)

Thanks for the report, confirmed here too!

I can see that the pages have an extra div or span with class
"vernacular" for the Hiragana text - I thought that
might be it, but the correct value is found by the equivalent
Palatina code. So it might be to do with how the WorldCat provider
downloads the HTML (AbstractProvider#transport).

I'll look into it further.
