If you look at the source code for the "full list" popup, the game names you identified are input/listed the same way, with the missing special characters.
However In Nomine displays correctly in the drop down list available from the Game System input field.
Checking that code reveals they're input/listed correctly.
HTML:
<option value="In Nominé">
Yesterday's Tomorrow and Zweihänder are also correct in the code, though those don't display in the drop down list as (I think) it's limited to 60 entries, so it cuts off in the V's.
I don't know if this is related to the Wiki issue at all, just saw your post and decided to poke at it and noticed the discrepancy which might be causing the issue you identified with the pop up system list. I don't even know enough about modern web programming to figure out if that list is being pulled from somewhere for each purpose, and so getting mangled in that process, or if it's manually input both times and one was correct and the other was not.
