I'm using Irrlicht 1.4.2 on Mac (simply because there isn't a 1.5 edition for Mac yet ), and I cannot enter fullstops into GUI textboxes.
That's about as much information as I can provide without giving you 200 source code files :/
---------------
randomMesh on IRC found a topic which has a fix (by ohanegby): Bugfix
OSX: Missing characters in keyboard input
The fix you linked to is already applied to Irrlicht 1.5. AFAIK, the only difference between the Mac version of Irrlicht and the standard one is it comes with OSX binaries. So just download Irrlicht 1.5, open the Xcode project in /source/Irrlicht/MacOSX and recompile.
However, when the 1.5 for OSX is released it will have a couple of extra bugfixes, so stay tuned!
Edit: There are some more broken keys, a lot of characters are missing including: ', `, |, $, %, &, (, {, }, # and €.
I've added a bug to the tracker here-
