This is the output you get if at some point UTF-8 data was interpreted as Latin1. For example:

let s = "Kawran Bazar FDC Road, East Nakhalpara, নিকেতন, ঢাকা, ঢাকা বিভাগ, বাংলাদেশ"
let utf8Data = Data(s.utf8)
let latin1 = String(data: utf8Data, encoding: .isoLatin1)!
print(latin1)

==> 

Kawran Bazar FDC Road, East Nakhalpara, নিà¦à§à¦¤à¦¨, ঢাà¦à¦¾, ঢাà¦à¦¾ বিভাà¦, বাà¦à¦²à¦¾à¦¦à§à¦¶

You should first try to fix this and remove this incorrect string creation. If you cannot, then you can round-trip it back through Latin1.

let latin1Data = latin1.data(using: .isoLatin1)!
let utf8String = String(data: latin1Data, encoding: .utf8)!

utf8String == s // true
