Sirichana is a monolinear Thai typeface with Light and Bold weights. The modern design is characterized by its traditional proportions but with almost geometric construction. Originally released by Linotype for digital photocomposition, it is now in OpenType format. This makes it possible to dynamically and precisely position the various levels of superscript and subscript vowel signs and tonal marks. In addition to this, the complete Unicode page range for Thai is covered to ensure flawless conversion between other OpenType fonts using Unicode. The accompanying Latin design matches well in scale and texture and supports most Western European languages making it ideal for setting bilingual texts.
