This is a file generated by a FileMaker script. I created the file by looping among the records in the ASCII.fmp12 file I uploaded and created one record that contained all of the glyphs - char(x) - in one field. This produced something like 1500 characters out of the 100,000 possible Unicode characters in the some of the latest fonts.
One source of information, out of date by several years, is http://www.alanwood.net/unicode/index.html
Open the file in Wordpad in windows and select your preferred font and see some of the glyphs that are available to you. Note that some of these may cause a crash when the field is clicked on but not if it is just viewed.
