character display

[AngeDieu]

#UpsilonNumworks#323
Describe the bug
I have 2 bugs :
-the first is on the grapher and the sequences applications, where the display of the exponent is bugged : you have an unknown character followed by the exponent value.
-the second is in python, where the percentage character is displayed as a space when placed in a string.

To Reproduce
Steps to reproduce the behavior:
e :

1. Go to graph app / graph
2. Click on a high number (such as 1.3 e¹²)
3. See error: sort of blank rectangle

"%" :

1. Go to graph app / graph
2. Click on a high number (such as 1.3 e¹²)
3. See error: sort of blank rectangle

Expected behavior

• the E symbol should be displayed as in calculation app
• the % symbol should be displayed instead of a blank space
