I am trying to find the best way to create an excel file which will be using
special characters like what you see for pronunciation in a dictionary like
long and short vowels. I will need to export this to a tab delemented TXT
file for InDesign to import. We have basically been using the Insert
Character in Excel to pick the correct special characters but they come in
all different fonts and do not work for exporting. Just gives my TXT file a
bunch of "?".

This is something new with me and I might have the lingo incorrect so any
ideas of how to go about this would be helpful. I think basically I just
need to know which font to choose in Excel that supports special characters
that can be seen in a basic Notepad TXT file.
