lasptyqu -- The only module in Frescobaldi with an incomprehensible name.
LAnguage-SPecific TYpographical QUotes.
This modules contains 'secondary' and "primary" opening and closing quotes for many
different languages.
Primary quotes are like double quotes in ASCII, and secondary quotes are like
single quotes.
A set of quotes (primary and secondary, left and right) is defined by
a named tuple(primary, secondary). Both the primary and secondary attributes
are also a named tuple(left, right). Use e.g. q.primary.left to get the left
primary quote of a quote set.
The quotes itself are simply unicode strings.
