Yes exactly, it would be cool to have such a satellite app
which can escape and unescape strings according to rules.
And which can also convert unicode literals to their ascii
analogues and back on the fly, this would very useful
for programming.
Probably it is a good idea to even include such thing
in Python package. So it would be a small standalone app
running parallel with text editor making it to copy paste strings.
