1. Yes you right it is like minus (HYPHEN-MINUS, decimal code 45). In english
keyboard it is only one symbol with short horizontal line (except LOW LINE,
decimal code 95 ). In Arabic keyboard i see symbol ـ (it is ARABIC TATWEEL),
but it is have same problem. Temporary solution is use Ctrl + "-" (but it have
visual problem, i will do new bug report)

Yes, minus sign is show after the number i.e. to the left side of the number
and if we continue type text it is show correct. But i not sure it is good for
mathematics formulas inside arabic text (like Alice in mirrorland).
2. BUT if you type only numbers in empty paragraph or before (from begin)
arabic text like "arabic_text 1-2-3-4-5" it is work good for RTL, but adding
any arabic letter in begin of string will do mirror number to "... 5-4-3-2-1
..."

Sure
