Package: libpoppler46
Version: 0.26.4-1
Severity: wishlist
Tags: patch
Forwarded: https://bugs.freedesktop.org/show_bug.cgi?id=80093
Hi,
evince, i.e. the PDF rendering engine behind it and thus poppler, fails
to render fi/fl ligatures for certain documents. This happens, if the
document has been created with the Times Type 1 font and then rendered
with the TeX Gyre Termes OTF font, which is a metric compatible
substitute. The reason is that in the Type 1 font the ligature glyphs
are called "fi" and "fl" whereas they are called "f_i" and "f_l" in the
OTF font.
Since both nomenclatures are right according to the Adobe specs, poppler
should search for the respective other if it canot find the requested
ligature glyph in the current font. The attached patch does exactly that
and I can confirm that it works. It has also been submitted upstream
[1], but they have shown no reaction recently. Thus I am asking you to
include it in the Debian package, which inturn might raise the incentive
for upstream to merge it as well.
Best Regards,
Fabian

Subject: [PATCH] if glyph name lookup failed, try alternate naming scheme for
ligatures
According to the Adobe spec., ligature glyphs may be named either e.g.
"fi" ot "f_i". If text has been set with a font using the one naming
scheme but is rendered with a font using the other, ligature glyphs
may be missing from the rendering. Therefore, if a glyph name lookup
failed, try again using the other naming scheme.
This happened e.g. for the "fl" and "fi" ligatures in texts set in
Times but rendered in Tex Gyre Termes.
Closes Bug #73291, Bug #80093.
