Fonts & Character Sets ⇒ Overleaf errors with Times New Roman and IPA

[latexnoob2022]

I have a LaTeX document with IPA symbols in built for XeLaTeX. I've used Times New Roman (which is unicode enabled) and am able to successfully build the document on my system (MaCOS).

However, on Overleaf, on the TeX code panel, the unicode is rendered correctly. When I try to build the PDF, this returns the following error:

Code: Select all

Missing character: There is no ̪ (U+032A) in font Times New Roman/OT:language=dflt;mapping=tex-text;!
Missing character: There is no ʈ (U+0288) in font Times New Roman/OT:language=dflt;mapping=tex-text;!

Has anyone faced issues with unicode-enabled fonts misbehaving on Overleaf like this? None of them except Doulos SIL are working for any special symbols when I build the PDF on Overleaf.

Thanks in Advance.

My code:

Code: Select all

\documentclass[12pt]{article}
\usepackage[a4paper,left=2.54cm,right=2.54cm,top=2.54cm,bottom=2.54cm]{geometry}
\usepackage{natbib}
\bibliographystyle{unsrtnat}
\usepackage{setspace}
\singlespacing
\usepackage{fontspec}
\setmainfont{Times New Roman}
\begin{document}

IPA STUFF:

t̪ ɞ ɠ ɢ ʛ ħ
\end{document}

I have the same warnings on my Linux machine. It is because the times.ttf that is used at this machine really does not provide the wanted glyphs. Maybe the font installed on your local machine has additional glyphs. Theoretically it would be possible to copy the font file to your project. But be careful! Commercial font licenses usually do not allow to do so!

Another suggestion would be to use a second font for the IPA stuff:

Code: Select all

\documentclass[12pt]{article}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\newfontfamily\IPA{Doulos SIL}
% \let\IPA\relax
\begin{document}

IPA STUFF:

{\IPA t̪ ɞ ɠ ɢ ʛ ħ}
\end{document}

On your local machine you activate the commented line in the example to use the main font instead of Doulos SIL for \IPA.

Thank you for your response! I did something like this as a workaround. What you said about the issue being the .ttf seems logical. I thought Times New Roman was unicode compatible, but if your system is giving the same error, then I suppose I will have to deploy 2 fonts.
