Arabic keyboard layout sends ligatures as one character (Laa Problem)

[AvidSeeker]

Ubuntu sends [Arabic ligature glyphs](https://en.wikipedia.org/wiki/Arabic_alphabet#Ligatures) as a single glyph. For example, Laa+Alif ligature "لا" (U+0644, U+0627) is sent as "ﻻ" (U+FEFB), and similarly for (ﻷ، ﻵ، ﻹ).

STEPS TO REPRODUCE

    Settings > Keyboard > Add default Arabic layout
    Type "ﻻ" (i.e: "b" in QWERTY keyboards)

OBSERVED RESULT
Output is ﻻ (U+FEFB)

EXPECTED RESULT
Output is لا (U+0644, U+0627).

To clarify for English speakers, this is like having a key to type a ligature. Say that you want to press "b" to type two characters: fi but instead you get fi as a single character. This is exactly what's happening with this issue.
