Helvetica has also learned to speak Thai: the Thai font designer Anuthin Wongsunkakon has created Thai versions of the classic typefaces Helvetica and Neue Helvetica. These versions are available in the weights Light, Regular and Bold, with the corresponding italic variants. Helvetica Thai harmonises perfectly with its Latin original and these two can thus happily be used in combination. With its pared-down and simplified form, Helvetica Thai replicates the appearance of modern Thai calligraphy.
Those who would like more information on this subject will find two interesting articles at Linotype.com. In the one, Anuthin Wongsunkakon describes the conversion process that resulted in the creation of Helvetica Thai. The other is an interview with the designer, in which he talks about various aspects of typography and typeface design.
