Bug ID: 698803
Summary: search regression: cannot search for α in mupdf-gl
Product: MuPDF
Version: 1.12
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P4
Component: mupdf
Assignee: mupdf-***@artifex.com
Reporter: ***@pragmata.tk

Tor,

this bug is related to bug #693724 and bug #697807, but I think this is a new
one.

In mupdf-1.12-rc1, α cannot be longer searched in mupdf-gl (it isn’t being
displayed). This is a regression from mupdf-gl in version 1.11 and it happens
both in Windows and Linux. This may be related to the replacement of GLFW with
FreeGlut.

In Linux only, another regression is that it is impossible to compose
diacritics plus searching (instead of "á", you get only "´a").

Could the issues be fixed for stable 1.12?

Many thanks for your help,

Pablo

Are you building against the system freeglut, or the one that we include in our
thirdparty git submodule / source archive directory?

If the former, then that's your problem. You NEED to use our included FreeGLUT
in order for non-ascii input to work.

I got the Windows binaries from https://mupdf.com/downloads/.

And with those binaries, α cannot be searched for.

Can you please attach the document with the 'α' that cannot be found?

mupdf-gl-1.12-rc1 getting "a" instead of "α"

BTW, I didn‘t attach the document before, because it is a question of the
viewer (with evince, Acrobat and mupdf-gl-1.11, it worked fine).

With mupdf-gl-1.12-rc1, when I type "α", I get an "a" (so the character to be
searched is totally different). This happens both in Windows 10 and in Wine.

With mupdf-gl-1.11, when I type "α", I get an "α" and this character can be
found. This happens in both Windows 10 and Wine.

I attach the screenshots.

Oh, so you mean you can't *type* the alpha character into the search box in
mupdf-gl...

That was an issue with FreeGLUT and how it handled keyboard input that meant
dead keys weren't being processed properly.

Fixed in commit 26006b55f02c8d0a4a90ffedb45f724798052ef2

Import FreeGLUT fixes for clipboard and unicode input.

Fixes issues with dead keys in unicode input.
