Arabic text shows strange characters الÙباىانگليسى،

I have Arabic text (.sql pure text). When I view it in any document, it shows like this:

حرÙاولالÙباىانگليسى،حرÙاضاÙهمثبت

But when I use an HTML document with <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>, it shows properly like this:

حرفاولالفباىانگليسى،حرفاضافهمثبت

How can I convert it to readable text?
