Python comes to the Casio fx-CG 50

I discovered that there is another MicroPython implementation for the Casio fx-CG50 called PythonExtra. The git repo is here: https://git.planet-casio.com/Lephenixnoi...a/releases. Download the `PythonExtra-pe-0.3.0-beta.zip` file, and copy over the `PythonExtra-pe-0.3.0.g3a` file to the CG50. The forum discussions are here (https://www.planet-casio.com/Fr/forums/t...extra.html), but the vast majority of the discussions are in French.

PythonExtra provides MicroPython v1.23.0 which solves many of the issues that I posted about. In particular, PythonExtra supports unicode strings and f-strings. However, the software is in "beta" phase, and has some deficiencies. Specifically, it currently has an even worse support for entering special ASCII symbols than Casio's MicroPython implementation: there is absolutely no ability to enter them at all through the calculator keypad, in both REPL mode and during `input()`. The maintainer responded that he is now aware of the problem, but will not be able to fix the issue for a while due to time constraints.
