Arabic-Latin Modern Fixed is an extension of TeX-Gyre Latin Modern Mono 10 Regular. Every glyph and opentype feature of the Latin Modern Mono has been retained, with minor improvements. On the other hand, we have changed the vertical metrics of the font. Although the Arabic script is designed to use the same x-size as Latin Modern Mono, the former script needs greater ascender and descender space. Every Arabic glyph in each Unicode-code block is supported (up to Unicode 7.0): Arabic, Arabic Supplement, Arabic Extended, Arabic Presentation-Forms A, and Arabic Presentation-Forms B. There are two versions of the font: otf and ttf. The opentype version is for print applications (and usually the default for TeX). The TrueType version is for on-screen applications such as text editors. Hinting in the ttf version is much better for on-screen, at least on Microsoft Windows. The unique feature of Arabic-Latin Modern is its treatment of vowels and diacritics. Each vowel and diacritic (ALM Fixed contains a total of 68 such glyphs) may now be edited horizontally within any text editor or processor. The author believes this is the very first opentype Arabic font ever to have this capability. Editing complex Arabic texts will now be much easier to input and to proofread.
