Christoph, could you please take a look?

Thanks.

I can't reproduce the test failure (and the test never failed for
me in the past), but I presume that that depends on the freetype
version and its configuration. Please store the created image as
PNG; something like:

  imagepng($im, __DIR__ . DIRECTORY_SEPARATOR .
  'imagettftext_charmap_order.png');

Then please make the image available somewhere.

Here you are http://picpaste.de/pics/bug73582.1479834942.png . Freetype 2.5.2, unfortunately I can't tell much about its configuration, as it's a precompiled package from the distro.

Thanks.

An update on this - i've got another vm with freetype 2.6.3 by default, and the test passes there. Seems to be indeed a version behavior difference.

Thanks.

Thanks for the image and the info that the test succeeds in the
other environment. I'll try to reproduce with FT 2.5.2 or FreeBSD,
so that I can debug.

I've still not been able to reproduce the failing test. I've tried
on Debian 8.4 with the default freetype2 package (2.5.2) and a
self-compiled freetype-2.5.2 one, and on FreeBSD 10.3 with the
default freetype2 package(2.6.3) and with the
freetype2-2.5.0.1.txz and freetype2-2.5.3_2.txz package. The test
always passes here.

I have not been able to find a FreeBSD freetype-2.5.2 package. :/

I'm afraid, I can't help here.

If it helps, i've reproduced the fail on Jessie as well, with the shipped freetype 2.5.2. I couldn't work on this in short term as well :/

Thanks.

Well, I tried again, and I can reproduce if I configure with
`--enable-gd-jis-conv`. Not sure, if that's the problem you've
found, but at least this has to be fixed. I'll look into it.

Thanks for looking into this again :) I obviously lost --enable-gd-jis-conv in the description, but it is indeed present in my config. Though, causing the test to fail only in certain env. Looks like there was always some bug, as the test is present for longer already, despite it doesn't fail with newer freetype.

Thanks.

Thanks for the quick confirmation. For me, the test fails even
with freetype 2.6.5 with `--enable-gd-jis-conv`. I wonder what the
image looks like in environments where the test suceeds with
`--enable-gd-jis-conv`. The expected image would be something like
<http://imgur.com/gallery/AETBl>.

There may indeed be issues with `--enable-gd-jis-conv`, but there
are definitely general issues with GD's freetype support[1][2],
besides that gdft.c has diverged between external and bundled
libgd, so IMHO, for now it might be best to just skip the test if
PHP has been built with JIS-mapped Japanese Font Support, i.e.
adding the following to the SKIPIF section:

  if(gd_info()['JIS-mapped Japanese Font Support'])
     die('skip JIS-mapped Japanese Font Support not supported');
