/*! String composition library for UTF-8.
* Defines compose::ucompose(fmt, arg...) for easy, i18n-friendly
* composition of strings. Uses Glib::ustring instead of std::string, which
* doesn't work with Glib due to character encoding troubles with stringstreams.
*
* Basic usage is like
*
* \code compose::ucompose("This is a %1x%2 matrix.", rows, cols); \endcode
*
* \sa See http://www.cs.aau.dk/~olau/compose/ or the included README for more
* details. Note that these refer to the official version, which uses different
* naming than this modified version.
*
* Modified from compose version 1.0.4. */
