With xeTeX and GFS Porson I can't use the digamma (ϝ) in text mode though the font seems to have the character (U+03DD GREEK SMALL LETTER DIGAMMA, UTF-8: 0xCF 0x9D, UTF-16: 0x03DD). Or is this a mathematical symbol? A similar question doesn't help, I don't want to switch to a math font, as it does with \digamma if I load \usepackage{mathspec} or don't prevent \usepackage{MnSymbol} from loading.

PS: GFS Porson doesn't actually have a digamma, I was mistaken. A replacement is not automatically chosen, so I want to select the character from a similar font.

Easiest sample (including some of the other things which didn't work)

% -*- mode: latex; TeX-engine: xetex; coding: utf-8; -*-
\newfontfamily\greekfont{GFS Porson}
% \usepackage{mathspec}
% \DeclareUnicodeCharacter{0370}{{\digamma}}
% \begin{greek}
  μῆνιν ἄειδε θεά \digamma ,\\
% \end{greek}
  • Sorry, but GFS Porson does not have ϝ. I looked with fontforge. The ϝ slot is highlighted in blue. Jul 3 '16 at 9:23
  • You could use CMU Serif instead. The advantage it, that you can use it as the main document font, because it has Latin and Greek alphabets (as well as Cyrillic). Jul 3 '16 at 9:27
  • @HenriMenke Sorry, I just used Gucharmap and looked into some porson-files, there the digamma seemed (for unexperienced eyes) to be included. Jul 3 '16 at 9:46
  • I'm voting to close this question as off-topic because it is about an issue (a non-existent glyph) that cannot be solved.

    You should perhaps rephrase your question a little. As is, it might suggest to other users that there is a digamma glyph in GFS Porson even though there isn't. Jul 3 '16 at 17:29

Find a font with the required glyph (not GFS Porson, which hasn't it) and use \newunicodechar for choosing it.



\setmainfont{GFS Porson}
\newfontfamily{\greekfont}{GFS Porson}

\newfontfamily\digammafont{Libertinus Serif}
\newunicodechar{ϝ}{{\digammafont\itshape ϝ}}


μῆνιν ἄειδε θεά ϝ


Don't load xltxtra: possibly the only feature one could need is sscript, that you disable. The fewer contortions, the better.

You may want to adjust the scale for the substitute font you choose.
