Replacing special characters when text mining

I am attempting to replace special characters inside of a dataset but not having much luck.

It seems as though RapidMiner is unable to understand those characters and is simply marking them as 
�. Non of the replace operators can seem to fix this issue. 

Should I be doing this inside of a generate attributes operator to account for this or is there a better way?

    Where is your dataset coming from? Operators like Read CSV that import external data have an "encoding" parameter. If you set the encoding correctly for your data import, you'll see all special characters.

    Another thing: -I is a capital "i".
