cmtiup – Upright punc­tu­a­tion with CM italic

The cmtiup fonts ad­dress a prob­lem with the ap­pear­ance of punc­tu­a­tion in italic text in math­e­mat­i­cal doc­u­ments. To achieve this, all punc­tu­a­tion char­ac­ters are up­right, and kern­ing be­tween let­ters and punc­tu­a­tion is ad­justed to al­low for the italic cor­rec­tion.
The fonts are im­ple­mented as a set of vf files; a pack­age for sup­port in LaTeX 2e is pro­vided.
