Enter Unicode characters in editors
This module provides a GPS action that, when executed, opens a
small command window. In this window, the user can either type the
numeric value or the name of a unicode character to insert at the
cursor position in the current editor.
For instance, select the menu /Edit/Insert Unicode, then type the
following decimal value:
928
This will insert a PI character. You could also insert it by typing
greek capital letter pi
or (in hexadecimal):
x3A0
Another GPS action is provided that describes the unicode character
currently under the cursor, including its numeric value and its name.
This action is called "Describe unicode char". It can be bound to a key,
assigned to a menu, or more easily executed through the startup script
execute_extended.py
