DilleniaUPC is a typeface designed for typesetting the Thai language in the Thai script. Its design is “sans serif” and linear-looking, with a strong vertical orientation and almost no contrast between thick and thin strokes. It has traditional loops (small circles at the extremes of some letters) and traditional forms for vowels and tone marks. Its bottom strokes are straight, with spurs on some characters. DilleniaUPC is appropriate for short passages of body text, or for headings and subheads.
DilleniaUPC was designed by Unity Progress Corp. and published in 1992. It has two weights, Regular and Bold, with complementary slanted (italic) styles for each. The font includes capitals and lowercase letters for the Latin alphabet, in a slab-serif style (that is, with stubby, squared-off serifs of even width).
