Description of problem: Applications compiled for GTK+ 1.2 and/or gnome-libs-1.4.2 no longer display UTF-8 characters properly on Fedora 10. The same application (compiled on Fedora Core 6) runs fine on Fedora Core 6 and Fedora 9. LANG=hu_HU.UTF-8 Version-Release number of selected component (if applicable): gtk+-1.2.10-66.fc10.i386 gnome-libs-1.4.2-10.fc10.i386 How reproducible: Always. Steps to Reproduce: 1. Install Fedora 10 2. Run a GTK1 app that uses some non-ASCII UTF-8 chars in widgets 3. Actual results: Non-ASCII characters display as some gibberish, i.e. like the UTF-8 chars and input (e.g. in a GTK_ENTRY) is interpreted as Latin1/Latin2. Expected results: Display every characters correctly. Additional info: I compiled glade-0.6.4-10 from an older Fedora system and it behaves the same, i.e. i18n correctly picks up Hungarian, but widgets (labels, menus, etc) display gibberish. The UTF-8 input seems to work and kept intact, because when I create a new window and set its label then the WM shows the correct text in the window caption.
The above was experienced with a freshly installed but then fully upgraded F10 system. I remembered seeing something similar on earlier Fedora systems, specifically on F8 that was later upgraded to F9, so all packages were kept during the upgrade. On that system installing all fonts by "yum install *fonts*" solved it. I tried installing all fonts on this F10 system and the problem disappeared as well. I don't know specifically which font solved it. Sorry for the noise.
