Just tested this a few minutes ago. For me, it works fine.
To make thinks less complicated, more information would be great!
Try to answer these questions:
– What version of WP and WR plugin do you have?
– Which characters (where in Unicode table can I find them?) did you try to replace?
I don’t know your system environment, but do you have direct access to your MySQL database (i.e. with a tool like phpMyAdmin)? If the answer is yes, could you check the table your_wp_prefix_here_word_replacer, expecially the column original, if your text is saved there as expected? (but be warned: If you don’t exactly what you’re doing, do not just edit any values in your database!)
