Many thanks for all the replies. <br><br> <br>I had tried to use primitives to compare fi with f{}i or simular, <br>but it didnt work as the primitives were comparing the input <br>before the ligatures were applied.<br><br> <br>Putting in a box and comparing the width with the width of the <br>idividual is perhaps an overkill for this...<br><br> <br><br>But the LuaTex suggestion was a good one - I never used it, but <br>searching on the internet for 'printing table of ligatures Luatex<br>produced a number of codes that apparently do it. I will try it<br>as it seems to be the easiesdt way.<br><br> <br><br>Thanks<br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br>> <br>> ------------------------------<br>> <br> Date: Wed, 14 Mar 2012 12:24:15 -0500<br>> From: <mskala@ansuz.sooke.bc.ca><br>> To: Unicode-based TeX for Mac OS X and other platforms <xetex@tug.org><br>> Subject: Re: [XeTeX] List of ligatures in a font<br>> Message-ID:<br>> <alpine.LNX.2.00.1203141216070.14366@tetsu.ansuz.sooke.bc.ca><br>> Content-Type: text/plain; charset="US-ASCII"<br>> <br>> On Wed, 14 Mar 2012, d fulano wrote:<br>> > how do I determine what are the "standard ligatures" in a font?It is not<br>> > obvious (especially for non-English languages), and they can also vary<br>> > in each font.
