I installed the 2019.1 community edition of PyCharm on a Windows 10 Pro yesterday.
Everything works perfectly except that I cannot type #, [, or ].
I use a French keyboard, and these keys are accessed with a combination of AltGr and an upper row digit (for example, AltGr+3 is #). This works in all other programs except PyCharm.
Copy and pasting these into PyCharm works, but it's very tedious.
