RE: Any way to remove ^L or ^M from some buffer outputs?

[Drew Adams <drew.adams@oracle.com>]

Use `query-replace' (`M-%') or `M-x replace-string'.

When prompted for what to replace, use `C-q' followed by the Control key (char) you want to replace. When prompted for what to replace it with, just hit `RET' (replace it with the empty string).

E.g., to remove Control-M chars:

M-x replace-string RET C-q C-m RET RET

(Using `C-m' is the same as using `RET' - same char.  But I write it that way to make it clear that `C-q C-m', which inserts a `C-m' char, is the string of chars to replace.)

If you want to be sure/careful of what you're doing, use `M-%' instead.  Once you see that it's doing what you want (by using `y' to replace some occurrences), just hit `!' to replace the rest of the chars.

In both cases, start with the cursor at bob (beginning of buffer), or `point-min' if you want to do it on the narrowed portion the buffer.
