What is the bug or the crash?

The --code flag, passed to qgis.exe, is meant to make QGIS execute a Python script after starting up. However, if the argument of --code has the ' character, QGIS isn't able to open the script. It seems that QGIS doesn't properly escape the filename.

Steps to reproduce the issue

1. Create a Python script containing a ' character, for example hawai'i.py.
2. Open Command Prompt.
3. Run QGIS with the script passed in the --code argument, .e.g "C:\\Program Files\\QGIS 3.40.2\\bin\\qgis-bin.exe" --code "hawai'i.py".
4. QGIS opens an error window containing the following error:

An error occurred during execution of following code:
with open('E:/tmp/hawai'i.py','r') as f: exec(f.read())


  File "", line 1
    with open('E:/tmp/hawai'i.py','r') as f: exec(f.read())
                                   ^
SyntaxError: unterminated string literal (detected at line 1)


Python version:
3.12.8 (main, Dec 20 2024, 15:21:15) [MSC v.1938 64 bit (AMD64)]

QGIS version:
3.40.2-Bratislava 'Bratislava', 14826ca1

Versions

Supported QGIS version

• I'm running a supported QGIS version according to the roadmap.

New profile

• I tried with a new QGIS profile

Additional context

QGIS ought to correctly escape the filename before plonking it into Python code.
