it seems that word processing doesn't work with regex

I plan to replace the symbol ---- with tab, So I try to do this. such as I have data like this: a----b----c.

the result should be a b c (I can't input tab key, So I use space instead), but the result is a*/tb*/tc

What to replace = {-String.Tab-}
