Hello and as-salāmu ʿalaykum!
I am working on an Arabic typeface and am facing few problems in the final font rendering in several software applications — the letters within the words appear as isolated (separate) characters, instead of connected letters, according to the Arabic script.
I tested the font across few softwares and compared it as well with Lalezar by Bornā Izadpanāh, available as Google Font as with other fonts, OS accessible.
The font has automatically generated OpentType features and is being exported into the Adobe Fonts folder.
The softwares that don’t support the connections are Adobe Illustrator CC 2017.1.0 (Mac OS / Adobe Fonts Folder exported), MS Word (Windows / installed in kind of font manager), Notepad (Windows / font manager), TextEdit (Mac OS / Font Book).
The softwares that support flawless the connections are InDesign CC 2017.1.0 (Adobe Font Folder / Adobe World-Ready Paragraph Composer is switched on), the handy Google Chrome extension called Font Changer and Adobe Illustrator Middle Eastern (screenshot by Bornā).
As it you can see I tryed in two platforms (Mac & Windows); two ways of installing (Adobe Font Folder & exported with a different name in a font manager, in order to avoid cache problems).
I designed the most of the glyphs without entry and exit anchors, as stated by Rainer. But tried also to implement them in few glyphs, but the result is the same.
Whenever I make a change in the Font Info I update and compile it before exporting. The dflt script is latn, but my font supports also a localisation in Arabic.
Honestly, I don’t know where the problem is and what should I do to solve it.
Thank you in advance,
Nikolay
P.S.
I realize my font could be optimized as design, but it is still in progress. However, this is not the focus of my question.
