I am having problem typing character glottal stop into a JTable,
and only 0241 and 0242 (hex: latin capital letter glottal stop, latin small letter glottal stop) those which were added in unicode version 5.0.
Using Windows XP, I can type these characters in Firefox, but not in JTable, or Notepad (where I tried to use same fonts as firefox should be using).
It works in linux though.
Windows XP seems to not support Unicode 5.0. Also, it depends on the installation, try installing support for asian languages, this adds fonts and other stuff.
