i’m wondering why kasha-ar.isol is set as a letter and all the arabic-mark.isol as mark.
Those FE76, FE78, FE7A, FE7C, FE7E are actually spacing glyphs composed from space and the non-spacing version.
Therefore, I think they should be considered as letters, not marks. But if considered marks, they all should.
Or is there any particular reason I don’t know about?
Hi,
In arabic we don’t have any mark as a letter, except the Hamza, kasra-ar.isol is should categorized as mark, anyhow you can change that by changing the glyph info, by clicking on [cmd + alt + i]
and simply you can change the glyph width to zero.
I guess the only use is when you write a grammar book.
I think it should be categorised as letter (even if it probably never make any difference.)
Unicode says it’s a space with a mark so I would consider this to be a letter.
I just wanted to point out that it’s the only mark that is categorised as a letter, so it’d be good to have the same subcategory for all the FE76, FE78, FE7A, FE7C, FE7E.
@qassimhaider Are you editing the GylphData.xml from within the Glyphs UI? If I hit cmd-alt-i I cannot edit anything, just see and create glyphs.
They are marked as <isolated> 0020 06xx (isolated presentation forms) in Unicode and are supposed to be KC-normalized (compatibility decomposition plus canonical composition). That means they are treated much like the spacing, non-combining accents in Latin, or an isolated Arabic letter. I would therefore probably not redefine them as Mark, because the idea is that they are treated as letters. E.g., in a text discussing marks, and you want to put an example in parenthesis, like ‘this diaeresis (¨)’.
How do I get that other window? I never heard of that.
And when I have it, how does it work? Does it make changes for one font-file without changing the GlyhData.xml?
Well, Sorry ,after some researches I did, and reviewing some fonts, yes it’s true that kasha-ar.isol as letter or they develop it to be as a letter, yes, true, it’s used in explaining the grammars, and for that case as letter is more practical… and for this of course you need to have width, but I don’t have any idea why these are marks FE76, FE78, FE7A, FE7C, FE7E !
and there is also the following as well: fathatan-ar.medi kasra-ar.isol kasra-ar.medi kashida-ar fatha-ar.medi damma-ar.medi … as letters …
You are right. They all should be the same category. I fix it.
But as ‘Mark/Spacing’ is treated the same as ‘Letter’ in Glyphs, I think I will set all of them in the ‘Mark’. that way they get sorted closer to the other marks and not among the letters.
