Language / Instruction how to install Polish diacritic letters on your computer [30]

I'm sorry to ressurrect this, but is there any way to be able to read the diacritic letters correctly on GG if I'm using an English operating system, like shown above?

I can input them just fine, and from memorizing I'm slowly being able to automatically recognize the words the distorted letters are in, but it'd be far better to be able to see what I write...
