If I do this: >>> (query-replace-regexp "[a-f]" "XXX")
it works correctly, replacing the letters a-f with XXX. If I do this: >>> (query-replace-regexp "[\140-\145]" "XXX") it does exactly the same thing. If I do this: >>> (query-replace-regexp "\224" "XXX") it works correctly, replacing the \224 char with XXX. If I do this: >>> (query-replace-regexp "[\220-\225]" "XXX") it does NOT work at all, and replaces nothing. ??????? What I want to do is find and optionally replace a range of characters from \200 to \277. How do I do that? John
