[Bug] Bad convertion CP1251 name

[Doumor]

Description

Bad convert CP1251 name.
Like this:

Ideally there should be readable Cyrillic words there.

I assume there should be a check for CP1251 in the code and a proper conversion for it. Right now it looks like CP1251 is being translated to ISO-8859-1. Люди -> Ëþäè and e.t.c.

Steps to Reproduce

Try to add song with CP1251 name.

Device

• Device: Infinix Note 30

Unfortunately, MediaStore does not parse them correctly. A possible solution would be #417.
