it seems like the additions in the translation files to support Oblivion Interaction Icons are out of date. Updating the following entries seems to make it work on the current version
The changes are from double to single quotes, the addition of the $ in the font face (escaped, took me a bit to realize I had to do that to make it work), the addition of the color entry, and the spaces before and after the letter that are present in some strings but not others.
