jinja2.exceptions.TemplateSyntaxError: unexpected char '\uf07c' at 67

[lesamouraipourpre]

I've just tried this with a fresh install of msys2
uname -a => MSYS_NT-10.0-19042 dolores 3.2.0-340.x86_64 2021-05-24 19:32 UTC x86_64 Msys
and it runs without error:

The unexpected char '\uf07c' is technically in the Private Use Area range : https://www.unicode.org/charts/PDF/UE000.pdf
I've seen it listed as folder-open in a Font : https://fontawesome.com/v5.15/icons/folder-open?style=solid

Can you try again with an upgraded msys2 and see if it still gives an error?

[lesamouraipourpre]

The unexpected char '\uf07c' is technically in the Private Use Area range : https://www.unicode.org/charts/PDF/UE000.pdf
I've seen it listed as folder-open in a Font : https://fontawesome.com/v5.15/icons/folder-open?style=solid

While reading through other issues, I've found the source of the '\uf07c'

Somehow the pipe character in the filename (not the best idea probably) somehow gets read as \uf07c which then of course is not correctly parsed.

I am running to similar issue on windows as well, any solution found yet?

[jepler]

The other issue I found was cookiecutter/cookiecutter#1632 and cookiecutter/cookiecutter#1636

One option we have is to switch to ansys-cookiecutter, fix any problems that arise due to the 2.x major version bump, and change our templates to use the workaround.

In any case, our CI should include "test that the cookie cutter works on Windows".

[jepler]

To try out the fix in #177:

• Install the 2.0.2 version of cookiecutter in either of these two ways: pip install cookiecutter@https://github.com/cookiecutter/cookiecutter/archive/2.0.2.zip or pip install ansys-cookiecutter
• Run cookiecutter as follows: cookiecutter https://github.com/jepler/cookiecutter-adafruit-circuitpython/archive/refs/heads/ansys-cookiecutter.zip
