The time has finally come when Unicode has specified a codepoint above U+FFFF which has a decomposition: U+16125 GURUNG KHEMA VOWEL SIGN AI, in Unicode 16 which the following commits will add support for. So far, we’ve managed to store the reverse-lookup from decomposed pairs to their composed form using a 16-bit integer. Now we have to switch to storing the composed form in a 32-bit `gunichar` as U+16125 won’t fit otherwise. This introduces no functional changes, but does double the in-memory size of the `compose_array` table from 9176 bytes to 19932 bytes. The code which uses this lookup table, in `gunidecomp.c`, was already implicitly converting the loaded value to a `gunichar`, so needs no changes. When we update to Unicode 16, the new `NormalizationTest.txt` file contains a test which will check that composed codepoints > U+FFFF work. Specifically, U+11391 TULU-TIGALARI LETTER AU is tested.

GLib
GLib is the low-level core library that forms the basis for projects such as GTK and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.
The official download locations are: https://download.gnome.org/sources/glib
The official web site is: https://www.gtk.org/
Installation
See the file ‘INSTALL.md’. There is separate and more in-depth documentation for building GLib on Windows.
Supported versions
Upstream GLib only supports the most recent stable release series, the previous stable release series, and the current development release series. All older versions are not supported upstream and may contain bugs, some of which may be exploitable security vulnerabilities.
See SECURITY.md for more details.
Documentation
API documentation is available online for GLib for the:
Discussion
If you have a question about how to use GLib, seek help on GNOME’s Discourse
instance. Alternatively, ask a question
on StackOverflow and tag it glib.
Reporting bugs
Bugs should be reported to the GNOME issue tracking system. You will need to create an account for yourself. You may also submit bugs by e-mail (without an account) by e-mailing incoming+gnome-glib-658-issue-@gitlab.gnome.org, but this will give you a degraded experience.
Bugs are for reporting problems in GLib itself, not for asking questions about how to use it. To ask questions, use one of our discussion forums.
In bug reports please include:
- Information about your system. For instance:
- What operating system and version
- For Linux, what version of the C library
- And anything else you think is relevant.
- How to reproduce the bug.
- If you can reproduce it with one of the test programs that are built
in the
tests/subdirectory, that will be most convenient. Otherwise, please include a short test program that exhibits the behavior. As a last resort, you can also provide a pointer to a larger piece of software that can be downloaded.
- If you can reproduce it with one of the test programs that are built
in the
- If the bug was a crash, the exact text that was printed out when the crash occurred.
- Further information such as stack traces may be useful, but is not necessary.
