TYPO3 Core

Typo3 4.0.4
Indexed Search 2.9.3
catdoc 0.91.5

I have configured indexed_search to index also external files. This works well for pdf, sxw, rtf, odt, ppt. But not for Word ".doc" - instead of the Text there are only question marks. It is surely a charset problem.

in a shell I could get the correct text from the file with the -8 option of catdoc:
catdoc -dutf-8 -8 worddok.doc

Is this a bug of catdoc? Should I use a newer version?
I have attached the file which could not get indexed correctly...
