Version: 2.4.3 (using KDE 4.4.3) OS: Linux Set Misc Console as the default font for the current profile (bizarrely, it is listed as "Console", not as "Misc Console". Build a project using make and mare sure there are warnings such as "warning: enumeration value ‘x’ not handled in switch". The left and right single quotation marks (wrappin 'x' in the message above) are rendered as white boxes. Same behavior in Kate. This is a regression as compared to KDE 4.3.5. Reproducible: Always OS: Linux (x86_64) release 2.6.31.12-0.2-desktop Compiler: gcc

Can't reproduce it with KDE-4.7.0 and Qt-4.7.3 . Feel free to reopen if this still happens in recent version.
