String and Unicode objects have one unique built-in operation: the
\code{\%} operator (modulo). Given \code{\var{format} \%
\var{values}} (where \var{format} is a string or Unicode object),
\code{\%} conversion specifications in \var{format} are replaced with
zero or more elements of \var{values}. The effect is similar to the
using \cfunction{sprintf()} in the C language. If \var{format} is a
Unicode object, or if any of the objects being converted using the
\code{\%s} conversion are Unicode objects, the result will be a
Unicode object as well.

\emph{formatting} or \emph{interpolation} operator. Given

result will be a Unicode object as well.
If \var{format} requires a single argument, \var{values} may be a
single non-tuple object. \footnote{A tuple object in this case should
