shell-filter-ctrl-a-ctrl-b

shell-filter-ctrl-a-ctrl-b is a compiled Lisp function in `shell.el'.

(shell-filter-ctrl-a-ctrl-b STRING)

Remove `^A' and `^B' characters from comint output.

Bash uses these characters as internal quoting characters in its
prompt. Due to a bug in some bash versions (including 2.03,
2.04, and 2.05b), they may erroneously show up when bash is
started with the `--noediting' option and Select Graphic
Rendition (SGR) control sequences (formerly known as ANSI escape
sequences) are used to color the prompt.

This function can be put on `comint-preoutput-filter-functions'.
