Not sure what the question is. A better approach to doing what?
I assuming you're doing tkinter (it is helpful if you mention the toolkit when
posting a
question). I'd create a function that you bind to all 'unicode buttons', and
let the
function insert the correct character depending on which button triggered it.
A possible way to do that is to use a lambda with a different parameter for
every
button, like this:
b1=Button(f, text='char1', command=lambda b=1: insert_char(b))
b2=Button(f, text='char2', command=lambda b=2: insert_char(b))
...etc..
def insert_char(b):
if b==1:
entrywidget.insert(0, u"\u20ac") # inserts € in the entry widget e
elif b==2:
entrywidget.insert(0, ...some other char...)
...
Or simply define a different command function for every button, then you don't
have to
use the lambda.
