The plugin written can be used in glyphs3, but cannot be used in glyphs2

It can be displayed and used in glyphs3, but not displayed in glyphs3 with an error:

It looks like you are doing string processing. The way strings behave is quite different between Python 2 and Python 3. Glyphs 2 uses Python 2 and Glyphs 3 uses Python 3. You would probably need to write the related code twice, once for Python 2 and once for Python 3, but it’s hard to tell without seeing code directly.

thanks very much!!!
