Bug ID: 163475
Summary: Single-letter Kashida
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]

Description:
Currently, applying Kashida is by adding "ـ" U+0640 ARABIC TATWEEL _between_
letters. However, a more elegant way is by stretching a specific letter within
the word. This method is popular with old scriptures, calligraphy, and
handwritten messages.
Here is a rough estimate of the algorithm for the improved Kashida.
- Start with the last word in a line, and apply stretching to the final letter
in that word.
- However, if the letter is not "stretch-able" (e.g: Arabic Meem م), then look
for middle-form Kaaf (ك) and stretch that
- If there is no Kaaf, apply the fallback Kashida by adding TATWEEL between
letters.
- TATWEEL is usually added to the last two connected letters. These letters are
not necessarily the last letters of the word since they could be in isolated
form (e.g: "الماء" --> "المـــاء") Notice that "اء" are isolated (they cannot
connect).
- Stretch-able letter forms are: كـ, ـن, ن, ت, ـت, س, ـس, ص, ـص, ـى, ى, ف, ـف
(where س and ت also their dotted variants e.g: ش and ث). Also have a look on
https://en.wikipedia.org/wiki/Arabic_alphabet#Table_of_basic_letters for
reference.
