Arial Unicode MS

From Free net encyclopedia

In digital typography, the TrueType font Arial Unicode MS is an extended version of the font Arial. Compared to Arial, it features slightly rounder glyphs for the Latin script, omits kerning pairs, and adds enough glyphs to cover a large subset of Unicode 2.1—thus supporting most Microsoft code pages, but also requiring much more storage space (22 megabytes). It also adds Han Ideographic layout tables, but unlike Arial, has no smoothing in the 14–18 point range, and contains Roman (upright) glyphs only; there is no oblique (italic) version. Arial Unicode MS is normally distributed with Microsoft Office, but it may also be purchased separately (as Arial Unicode) from Ascender Corporation, the only company Microsoft allows to license the font.

History and availability

Arial was designed by Robin Nicholas and Patricia Saunders in 1982. It was later extended as Arial Unicode MS by Monotype Typography (now Monotype Imaging) under contract to Microsoft. Monotype Imaging still owns the Arial and Arial Unicode MS trademarks, but Microsoft retains exclusive licensing rights to the fonts. Microsoft currently licenses the font exclusively to Ascender Corporation, which sells it for approximately $99 per 5 users.

From mid-2001 through mid-2002, Arial Unicode MS was also available as a separate download for users of the standalone version of Microsoft Publisher 2000 SR-1, which did not ship with the font.[1] The freely downloadable version was withdrawn after Microsoft Publisher 2002, which included the font, began shipping.[2] Since the withdrawal coincided with the withdrawal of the free downloads of Microsoft's "Core fonts for the Web", there was also speculation, at the time, that the font was pulled because it was being illegally redistributed by vendors of non-Microsoft operating systems.[3]

Bugs

Image:Arialunicodebug.png All versions of Arial Unicode MS deal with double-width diacritic characters incorrectly, drawing them too far to the left by one character width. According to the Unicode Standard 4.0.0, section 7.7 combining double diacritics go between the two characters to be marked. However, to make text look correct in Arial Unicode MS, the double-width diacritic must be placed after both characters to be marked. This means that it is not possible to make text that renders these characters correctly in both Arial Unicode MS and in other (correctly designed) Unicode fonts.

This bug affects the rendering of text written in the International Phonetic Alphabet.
