'''Arial Unicode MS''' is a [[TrueType]] font and the extended version of the [[typeface|font]] [[Arial]]. Compared to Arial, it includes higher line height, omits [[Kerning#Kerning pairs|kerning pair]]s and adds enough glyphs to cover a large subset of [[Unicode]] 2.1—thus supporting most [[Microsoft]] [[code page]]s, but also requiring much more [[computer storage|storage]] space (22 [[megabyte]]s).<ref>{{cite web|url = http://support.microsoft.com/kb/q287247/|title=Article Q287247: Description of the Arial Unicode MS font in Word 2002|date = 2006-07-27|publisher = [[Microsoft Knowledge Base]]}}</ref>  It also adds [[ideogram|Ideographic]] layout tables, but unlike Arial, it mandates no [[Spatial anti-aliasing|smoothing]] in the 14–18 [[point (typography)|point]] range, and contains Roman (upright) glyphs only; there is no oblique ([[italic type|italic]]) version. Arial Unicode MS was previously distributed with [[Microsoft Office]], but this ended in 2016 version. It is bundled with [[Mac OS X v10.5]] and later.  It may also be purchased separately (as ''Arial Unicode'') from [[Ascender Corporation]], who licenses the font from Microsoft.

When rendered with the same engine and without making adjustments for the different font metrics, the [[glyph]]s that appear in both Arial and Arial Unicode MS appear to be slightly wider, and thus rounder, in Arial Unicode MS. Horizontal text may also appear to have more inter-line spacing in Arial Unicode MS. This is due to larger bounding boxes (Arial Unicode MS needs more room for some of its extended glyphs) and the limitations of renderers, not changes in the glyph shapes. The lack of kerning pairs in Arial Unicode MS may also affect inter-glyph spacing in some renderers (for example the Adobe Flash Player).

Arial Unicode MS also includes [[Hebrew]] glyphs different from the Hebrew glyphs found in Arial. They are based on the shapes of the Hebrew glyphs in [[Tahoma (typeface)|Tahoma]], but are adjusted to the weight, proportions and style of Arial.
