Is this really what the standard says, because '\\' is not a character, but
2 characters. They could use "\\" but if a backslash is between single
quotes, it loses its special meaning. The only way to get a backslash
when using single quotes that I've found is to end the single-quote
then use the backslash. So if you wanted to insert single quotes in
a string that is single-quoted, you would have to do this:
'this is a single-quote(SQ) quoted string using a SQ ('\'') within
the single quote.'
Alternatively using double-quotes or another quoting
mechanism might be preferable.
I find it odd that the standard would try to use a backslash within
a SQ'd string as a literalizer.
