There was an earlier item editor, available
here, but I don't recall if it could change an item's name. The following topic contains some information on manually editing the items.000 file.

I have not tried to do any translating, but at some point you will probably need to resort to a hex editor. There are various freeware programs, such as
Frhed,
XVI32 or those listed
here, etc. I have not searched for hex editors in years, or tried recent versions of any. Also, when I did last test hex editors, I required a file comparioson function, so may have dismissed some that would be perfectly suited for translating.
I use Hackman (v7.02
download 3.05MB); the 8.x release introduced a low file size limit in the freeware version, while there is only a demo of the current 9.x release on its
homepage.
The following topics may give you a bit of an introduction to hex editing.
