Editing Arial Unicode MS (section)

==Bugs==
[[Image:Arialunicodebug.png|frame|right|Demonstration of the double-width [[diacritic]] bug in Arial Unicode MS. The first row shows how Arial Unicode MS incorrectly renders a diacritic that is correctly placed between the letters "k" and "p". The second row shows how the diacritic is rendered in the correct position only if placed after the "p". The third row shows how the correct placement is rendered in TITUS Cyberbit Basic, which does not have the bug.]]
All versions of Arial Unicode MS deal with double-width [[diacritic|diacritic characters]] incorrectly, drawing them too far to the left by one character width. According to the [https://www.unicode.org/versions/Unicode4.0.0/ch07.pdf 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]] and in [[American Library Association-Library of Congress Romanization Tables|ALA-LC Romanization]] for non-Latin-script languages. If the displayed font in your browser draws the diacritics correctly, they should appear over the characters: k͠p, k͡p.
Furthermore, [[Combining Half Marks|halves of double-width diacritics]] are rendered as spacing characters.

The minuscule letters that form the [[Typographical ligature|ligatures]] fi, fl, ffi, ffl, long st, and st are not connected, except for the two f's in the ffi and ffl ligatures. As there is no semantic difference, nothing mandates that these must be connected, and they are indistinguishable from the individual letters placed next to each other.

Arial Unicode MS is unable to render some [[Arabic script in Unicode|Arabic]] characters, particularly those used in [[Sindhi Language|Sindhi]], in their connected forms, showing only their isolated forms instead.
