I am using polyglossia for Bangla. But I cannot do bold or italic. May be the Bangla font "Kalpurush" is causing the issue as English "Times New Roman" font is just working fine. Here is a download link to "kalpurush.ttf" file. can any one help? Thanks in advance. :)

here's the code. 

% !TEX program = xelatex
\documentclass[a4paper,12pt]{article}
\usepackage{polyglossia}
\setmainlanguage[numerals=Devanagari]{bengali}
\setotherlanguage{english}
\newfontfamily\englishfont{Times New Roman}
\newfontfamily\bengalifont[Script=Bengali]{Kalpurush}
\begin{document}

সাধারন ফন্ট, \textbf{বল্ড ফন্ট}, \textit{ইটালিক ফন্ট}\\

regular font, \textbf{bold font}, \textit{italic font}\\

\englishfont{regular font, \textbf{bold font.}, \textit{italic font}}

\end{document}

  • The font doesn't appear to have the required forms. A single .ttf file contains just one shape/weight. – egreg Apr 02 '20 at 14:49

    You could try the FakeBold and FakeSlant options, see the documentation of fontspec. – Ulrike Fischer Apr 02 '20 at 15:37
  • @UlrikeFischer I am really new to latex. I tried but could not figure out how fontspec really works. It would be a huge help if you could post a answer using fontspec. – Soyeb Jim Apr 02 '20 at 16:03

    you are already using fontspec. I don't have your font and can't test. Try something like \newfontfamily\bengalifont[Script=Bengali,BoldFont={Kalpurush},BoldFeatures={FakeBold=5},ItalicFont={Kalpurush}, ItalicFeatures={FakeSlant=5}]{Kalpurush}. – Ulrike Fischer Apr 02 '20 at 16:14

You have a single instance of the font, in regular weight, so no boldface is available.

If I use a different Bengali font, I get boldface. No italics, though: is it used in Bengali?

\documentclass[a4paper,12pt]{article}
\usepackage{polyglossia}

\setmainlanguage[numerals=Devanagari]{bengali}
\setotherlanguage{english}
\newfontfamily\englishfont{Times New Roman}
\newfontfamily\bengalifont{Bangla MN}[
  Script=Bengali,
  BoldFont=* Bold,
  ItalicFont=*, % just not to get annoying warnings
]

\begin{document}

সাধারন ফন্ট, \textbf{বল্ড ফন্ট}, \textit{ইটালিক ফন্ট}

regular font, \textbf{bold font}, \textit{italic font}

\englishfont{regular font, \textbf{bold font.}, \textit{italic font}}

\end{document}

This can be easily done by the bangla package.

\documentclass[a4paper,12pt]{article}

\usepackage{bangla}


\begin{document}


\banglatext{সাধারন ফন্ট}, \banglabold{বল্ড ফন্ট}, \banglaitalic{ইটালিক ফন্ট}


\end{document}
