# How to change the language, for just a few lines in a template? [closed]

I am using a Persian (thesis) template and in the references, there is a problem. In fact, some of them, contain a formula and since the template considers the numbers in the context of a Persian master, the numbers in these references are in Persian, and the rest of these titles are in English. Is there any environment to solve this problem and change the numbers style to English? The template can be found here.

• Please provide a complete, minimal example that produces that bib entry (and its erroneous output), and also include relevant packages that you are loading. – Troy Aug 4 '18 at 14:32
• use package biblatex and define the langid field in the bibliography entry. – user2478 Aug 4 '18 at 17:56
• @Herbert: Tnx. can U plz bring an example? – Perfect Fluid Aug 4 '18 at 18:34
• Your template uses the old BibTeX format. I cannot test it with biblatex, too many problems with package xepersian. – user2478 Aug 4 '18 at 19:01
