When I compile the code below with XeLaTeX (using TeXworks), ligatures for Times New Roman do not show. Instead, I just get singular characters.

\documentclass{article}

\usepackage{fontspec}

\setmainfont[Mapping=tex-text,Ligatures=TeX,Scale=1.05]{Times New Roman}

\begin{document}

Ligatures: fi fl ffl

\end{document}

I have tried Ligatures={Common} and Ligatures={Common, TeX} instead of Ligatures=TeX (found in this answer), but there is no difference. I've checked the font map for Times New Roman (v.6.85) and the Unicode characters FB01 and FB02 are present with the expected ligatures.

However, when I do not specify the font, the above (thus set in Computer Modern) does have ligatures.

It is not terribly important for me to use Times New Roman, but it has IPA characters (which I need for my linguistics thesis), and old style numerals and small caps (which I like).

Is there a way for me to get Times New Roman to show these ligatures?

    Imho they are not activated and can't be accessed by the ligature option. But if the glyphs are there then it should be possible to create a mapping file to use them. tex.stackexchange.com/questions/227341/… – Ulrike Fischer Feb 25 '15 at 15:53

    Linux Libertine O is a good alternative with old style numerals, small caps (even bold small caps), full IPA coverage (except for the labiodental flap [ⱱ]), and decent diacritic placement. It has the ligatures you want, plus several more, and they work fine with XeLaTeX, even decomposing correctly in the PDF for searching and copy-and-pasting. I use fontspec to access the lining numerals in glosses and example numbers and the old style numerals elsewhere in my thesis. – Jason Zentz Feb 25 '15 at 16:55
  • That is a beautiful-looking font, Jason Zentz. I might just try it. Regarding your last sentence: how did you make fontspec use lining numerals in glosses and examples but not elsewhere? I looked at the documention but I'm still unsure. – P. de Rijke Feb 25 '15 at 21:43
  • Sorry, didn't know about the author-tag function. How did you set up fontspec the way you described @JasonZentz ? – P. de Rijke Mar 2 '15 at 8:25
  • @P.deRijke, I can't really fit my code for that in a comment, and I think it would be better suited as an answer to a follow-up question, anyway. So feel free to ask that in a new question and I'd be happy to answer. – Jason Zentz Mar 2 '15 at 17:33

Prepare a new map file, I called it rijke.map

; TECkit mapping for TeX input conventions <-> Unicode characters

LHSName "TeX-text"
RHSName "UNICODE"

pass(Unicode)

; ligatures from Knuth's original CMR fonts
U+002D U+002D           <>  U+2013  ; -- -> en dash
U+002D U+002D U+002D    <>  U+2014  ; --- -> em dash

U+0027          <>  U+2019  ; ' -> right single quote
U+0027 U+0027   <>  U+201D  ; '' -> right double quote
U+0022           >  U+201D  ; " -> right double quote

U+0060          <>  U+2018  ; ` -> left single quote
U+0060 U+0060   <>  U+201C  ; `` -> left double quote

U+0021 U+0060   <>  U+00A1  ; !` -> inverted exclam
U+003F U+0060   <>  U+00BF  ; ?` -> inverted question

; additions supported in T1 encoding
U+002C U+002C   <>  U+201E  ; ,, -> DOUBLE LOW-9 QUOTATION MARK
U+003C U+003C   <>  U+00AB  ; << -> LEFT POINTING GUILLEMET
U+003E U+003E   <>  U+00BB  ; >> -> RIGHT POINTING GUILLEMET

; additions for f ligatures
;U+0066 U+0066 U+0069 <> U+FB03 ; LATIN SMALL LIGATURE FFI
;U+0066 U+0066 U+006C <> U+FB04 ; LATIN SMALL LIGATURE FFL
;U+0066 U+0066        <> U+FB00 ; LATIN SMALL LIGATURE FF
U+0066 U+0069        <> U+FB01 ; LATIN SMALL LIGATURE FI
U+0066 U+006C        <> U+FB02 ; LATIN SMALL LIGATURE FL

The basis is the standard tex-text.map file found in TeX Live. The “ff” ligatures are commented out, because my copy of Times New Roman doesn't support them.

Now compile it

teckit_compile rijke.map

This will produce a rijke.tec file; if you keep it along your document, the input

\documentclass{article}

\usepackage{fontspec}

\setmainfont[Mapping=rijke,Scale=1.05]{Times New Roman}

\begin{document}

Ligatures: ff ffi ffl fi fl 

\end{document}

will produce

  • Thanks for the detailed solution. I did not know this was possible. – P. de Rijke Feb 25 '15 at 21:39
  • It worked for me. However, my copy of Times New Roman also does not support "ff" ligatures. Any idea where and how to get one that does? – Frank Ejby Poulsen May 18 '16 at 22:32
  • @FrankEjbyPoulsen Try TeX Gyre Termes – egreg May 19 '16 at 5:54
  • How do I create a .map file? – ahorn Apr 28 '17 at 9:39
  • @ahorn I usually copy tex-text.map in a working directory, with a different name, and modify it like in the example above. The base file is found in the TeX tree; in TeX Live it is at /usr/local/texlive/<year>/texmf-dist/fonts/misc/xetex/fontmapping/base/tex-text.map (use the proper value for <year>, such as 2016). – egreg Apr 28 '17 at 9:50

In Windows 10 1803, it seems Times New Roman has been updated to version 7.00, and some (more) ligatures have been added (but into dlig lookup, rather than the more widely-used liga). We can then use fontspec to turn on this feature:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\begin{document}
\verb|Default:                  |
fi fj fl ff ffi ffj ffl Th

\verb|Ligatures=Discretionary:  |
{\fontspec{Times New Roman}[Ligatures=Discretionary] % or `Ligatures=Rare`
fi fj fl ff ffi ffj ffl Th}
\end{document}
