The absence of RTL UI causes some visual issues. When it comes to the UI strings, sometimes there is a workaround that translators can do to fix things, but they have nothing to do to align strings to the right or to fix visual issues that appear in actions, such as bots commands, search results, replied messages, send without sound, markdown links... etc
One of these visual issues, which is related to numbers, appears only if both iOS and Telegram language is a RTL language.
Translators who don't have iOS or don't use a RTL language in Telegram every day or periodically, may not know about these issues.
Use any RTL languages in Telegram from Settings> Language.
To reproduce some visuals related to numbers, you may have to change your device language too.
The user interface is aligned to the left.
Any iOS device with any RTL language: Arabic, Persian or Farsi, Hebrew, Malay Jawi.
