Thanks!

    Ooops. I lied. We stopped suppressing ligatures at some point. Brain fail.

    When we did suppress it, we used this code an ACL in Editor's custom/init
    folder:
    $ENV["APTLIGATURESENABLED"]="no"

    OR in a batch file used to start Editor like this:
    set APTLIGATURESENABLED=no

    We may have also set it from PE's custom folder but I can't tell for sure
    anymore.

    We had problems with ligatures with Arbortext 6 and Windows 7. It seemed that Arbortext 6 was still using XP font definitions. I hope the description and solution below help.

    Examining the Arial [1] and Times New Roman [2] fonts shipped with Win7, we see that "Latin Small Ligature Fi" is located a code point U+FB01 and "Latin Small Ligature Fl" is located a code point U+FB02. Examining the same TTFs [3] we find these glyphs located at these standard points but also at U+F001 and U+F002 respectively, which is a private use area of the Unicode space. On the Win7 verisons of these fonts there is no glyph defined at the U+F001 and U+F002 code points.
    [1] Font name: Arial, Version: Version 5.06, OpenType Layout, Digitally Signed, TrueType Outlines: arial.ttf, ariali.ttf, arialbd.ttf, arialbi.ttf
    [2] Font name: Times New Roman, Version: Version 5.07, OpenType Layout, Digitally Signed, TrueType Outlines: times.ttf, timesi.ttf, timesbd.ttf, timesbi.ttf
    [3] OpenType Font, Digitally Signed, TrueType Outlines, Typeface name: Arial, File size: 359 KB, Version: Version 3.00, Typeface (c) The Monotype Corporation

    You can also disable ligatures in AE 5.4 in the FOSI:

    <docdesc>
    ...
    <lettersp allowligs="0">
    ...
    </docdesc>

    or in a .tmx file for the doctype:

    \ligaturesenabled=0

    I haven't used AE 6 yet, perhaps someone else can say whether these are still usable.

    Disabling ligatures in general was a solution we considered, but we had too many existing files that would make this impractical. We had to fix the fonts.

    FYI - pltotf.exe and tftopl.exe are located in ...PTC\Arbortext Editor\bin\x86
