add escape sequence interpretations for OSC strings #45
Description
I believe that currently we do not process escape characters inside OSC strings when they are specified via the "QSC" human-compatible text. So, for example, if someone provides the following string to messageWithString::
/cue/my/message "a string where I want \n a newline"
It will generate an OSC message with a string argument that contains \n rather than an ASCII newline character.
I think we should probably process some escape sequences inside string arguments. Maybe these:
\n: new line\r: carriage return\t: horizontal tab\v: vertical tab\f: form feed / new page
I think we'd change this somewhere around here:
