Lvgl: letter ى Arabic processing error

[ashrafkamel5]

Describe the bug
when Having an Arabic font that covers only the Arabic Presentation Forms-B.
the letter ى produces a missing glyph error.
explain
I found an error in the table of Unicode at ap_chars_map[] at lv_txt_ap.cfile
fix
at line 72
add this
{39, 0xFEF0, 0, 0, -1, {1, 0}}, // ى

I didn't want to delete the line existing at 72. because even if I think it is a mistake and the Unicode there is a duplicate of the one at 74
but yet. it doesn't harm being there.
and maybe it works fine with other forms for Persian writing, I don't know we should ask Mr. Hamid who wrote the file.
so just adding that line fixes it.
Screenshots
look at the keyboard and the missing letter.

Thank you!
@hamidrm, could you take a look at this?

@ashrafkamel5 You are right! It was my mistake. I thought the glyph of 0x6CC and 0x649 are the same (Although, In the Persian, they are the same!). According to https://en.wikipedia.org/wiki/Arabic_script_in_Unicode, you are right.
So, we should replace your change ({39, 0xFEF0, 0, 0, -1, {1, 0}}, //ی), with current line 72.
Thank you!

It's great adding full Arabic support to the library

@kisvegabor there is a small bug at dropdown widget
lv_dropdown_add_option
Doesn't process Arabic letters.
You need to add the lv_txt_ap_proc there

@kisvegabor
and the window's name also needs the same fix 😆
lv_win_set_title
it would be repetitive if I did an issue for both of them
hope you just fix them ❤️
really hyped for the upcoming release!

@ashrafkamel5
I've fixed both the dropdown and window, thanks for the report.

@hamidrm
Thanks for looking into it.
Could send a PR to fix that Arabic letter.
