Link to issue number:

None

Summary of the issue:

Errors in the source code are indicated visually by "^" characters and has become more precise with Python 3.11.
However, the characters used in log viewer or python console have not a fixed width so:

• visually, the wrong place of the source code is indicated
• for blind people, going on the error marker ("^" characters) and pressing upArrow to jump at the same column position in the source code's line is useless because the cursor does not land in the same column.

Description of user facing changes

Use a fixed width font in the log viewer and in the Python console.
In the Python console, only the output field is impacted by vertical alignment considerations; however, for visual consistency I have modified both the input and the output fields.

Description of development approach

Change the log viewer's font to 'Consolas' which has fixed width and which is the one used in Notepad.

Testing strategy:

Manual tests:

• Tested visually that the log viewer and the python console is using a fixed width.
• Tested that vertical navigation is OK from error markers in a traceback
• [ ]: Test required from a sighted person. (cc @Qchristensen or @gerald-hartig ?) to check the general appearance of the log viewer and python console for which I am not relevant.
