Glyph naming confusion


I am trying to build a latin extended character set. I am using Alphabet Type Builder. Some of the glyphs from the builder are named by their unicode.
For exemple uni0122 is Gcommaaccent or uniFB01 is fi.
Which of the two naming convention should I use?


Does this tutorial help:

great help, thanks

You can create them all with their uniXXXX names, and they are renamed automatically, provided you do not have Font Info > Other Settings > Use custom naming set.

Otherwise, you can force renaming with Glyph > Update Glyph Info.
