Arabic letter mark
The Arabic letter mark (ALM) is a non-printing character used in the computerized typesetting of bi-directional text containing mixed left-to-right scripts (such as Latin and Cyrillic) and right-to-left scripts (such as Persian, Arabic, Syriac and Hebrew).
Similar to Right-to-left mark (RLM), it is used to change the way adjacent characters are grouped with respect to text direction, with some difference on how it affects the bidirectional level resolutions for nearby characters.
Unicode
In Unicode, the ALM character is encoded at U+061C ARABIC LETTER MARK (HTML ؜
).
In UTF-8 it is 0xD8 0x9C. Usage is prescribed in the Unicode Bidirectional Algorithm.
gollark: So the general principle is "only obey governments I like"?
gollark: Any good robot overlord probably has EMP-hardened backup systems.
gollark: I don't think the constitution forbids that, so you could at least say that in *that instance* he does!
gollark: No, some of it just seems to indicate insanity.
gollark: Hey, don't discount the other bad stuff he does.
