[ros-diffs] [ablackmann] 43949: Implement getCharacterInfo so the tool can now handle most LAYOUT entries, but not complicated ligature entries (dead keys are fine though). Also cleaned up the parsing loop of DoLAYOUT to avoid a goto, and finally added detection of SGCAP entries (in which case the tool will fail, since these are complex and not needed for now). The main parsing loop is pretty much done, now the tool "just" has to merge the states and perform a check for duplicate entries. Then it'll be ready to generate the output files.
