OpenTTD/src/misc_gui.cpp
rubidium 61e97110c9 (svn r15765) [0.7] -Backport from trunk: 
- Change: [NewGRF] Expose GRF ID of engines in var action property 0x25 (r15739)
- Fix: Add Engine::GetDisplayDefaultCapacity() and use it everywhere, so CB 36 is also used everywhere (r15763)
- Fix: [Windows] Inlined UTF-8 characters (in the source code) are not handled properly on Eastern versions of Windows so escape them (r15762)
- Fix: [Windows] On some system searching a font using its English name fails. So now we search the font using the localised name and use the English name for the final 'validation' only (r15757)
