TorniaiSansOsfUT was a special version of the Torniai Sans type family from Unifonts (also known as Unitype). The letters were the same as in the standard TorniaiSansUT family; what changed were the numbers. The "Osf" in the name stands for old-style figures.
What are old-style figures? In most fonts the digits 0–9 all stand at the height of capital letters ("lining figures"). Old-style figures behave more like lowercase letters instead: in the usual arrangement, 0, 1 and 2 sit at the height of small letters, 6 and 8 rise above it, and 3, 4, 5, 7 and 9 drop below the line. Because of this, numbers blend into running text instead of standing out, which is why typographers often prefer them for books, articles and other long text, while lining figures suit tables, headlines and all-caps settings.
Why a separate font? Before the OpenType format, Type 1 and TrueType fonts had room for only one set of numerals. A foundry that wanted to offer both styles had to release them as separate fonts – which is exactly what Unifonts did with TorniaiSans and TorniaiSansOsf.
This page covers the Regular Italic style for Windows (PC), sold on its own. The Unifonts listings preserved in this catalog also include Light, Regular, Bold and Black styles of TorniaiSansOsfUT, each with an italic, plus a complete family pack and Mac editions.
Unifonts, run by Victor de Castro from Monroe, New York, sold around 1,100 fonts in Type 1 and TrueType formats. Its website is no longer online, so this font can no longer be licensed. This page is kept as a historical record.
