I've slightly misunderstood how the ICU Data Library Customizer works. I thought it would generate a icudtXX.dll, but it generates a .dat file to be used in the compilation of ICU. So now that I know that I have to re-build ICU with this .dat file, my question are: 1. Is it safe to replace the three icuXXXX.dll DLL files without also re-building Qt, provided that I use the exact same ICU version, compiled with the exact same compilation flags, but with a different .dat file? 2. If so, which parts of the .dat file can I safely exclude with the ICU Data Library Customizer? I don't think I need any of the features which Qt uses ICU for, but are there some parts that must be included for Qt to function at all? 3. Where can I find out how the ICU bundled with official Qt builds was built? Cheers, Elvis > > My questions are: > > 1.
