utils: coloransi: Escape Unicode U0001 and U0002 non-printable characters.
Fixes
#13637.
These Unicode characters, would cause problems when processed by LaTeX
to generate the info or PDF documentation targets.
* IPython/utils/coloransi.py (InputTermColors): Escape the backslashes
in \001 and \002 so that they are shown as literals '\001' and '\002'
strings in the Sphinx-generated documentation rather than as
non-printable Unicode characters.
