Can't launch non-Steam games containing a single quote ' in their path

[Silejonu]

Your system information

• Steam client version (build number or date): 2022-06-07 (1654574690)
• Distribution (e.g. Ubuntu): Arch Linux with GNOME, up-to-date
• Opted into Steam client beta?: [Yes/No] no
• Have you checked for system updates?: [Yes/No] yes

Please describe your issue in as much detail as possible:

Adding a non-Steam game which has a single quote (') in its name results in the game not launching.

Example target: steam -applaunch 1118310 -L "/home/silejonu/.steam/steam/steamapps/common/RetroArch/cores/sameboy_libretro.so" "/home/silejonu/ROM/Game Boy/Legend of Zelda, The - Link's Awakening (France).zip"

Steps for reproducing this issue:

1. Add a non-Steam game with a single quote (') in its name
2. Launch the game through Steam
3. The game-initialisation pop-up appears, then disappears immediately
4. Nothing happens

Additional info

• Double-quoting (") the path does not help
• Escaping (\) the single-quote does not help
• Removing the singe-quotes from a game executable will allow Steam to launch it

Additional info after further testing:

I tried running "/home/silejonu/test'.sh", and it launched successfully.

So the issue may be related to -applaunch, or RetroArch.
