Zeus reports an incorrect error message if you search for an UTF-8 character and it is not found:
1. Open any text file that does not contain the character ” (U+201D, Right double quotation mark, 0x0912).
2. Search, using Alt-S, for that particular character (copy and paste from above).
3. On the left side of the status bar in the bottom should appear a message like this:
Reached the end of document and the search string 'â€' was not found.
Seems like an old piece of code that hasn't been updated to handle Unicode just yet

Cheers,
