[Fixed][Win32] Load games from command line and unicode filenames

[CiroConsentino]

Hi,
thank you so much for this awesome PSP emulator for Windows. I'm implementing Unicode support in my frontend EmuCon, and I'm trying to load games with Unicode filename. The frontend have a PSP system and PPSSPP is supported.

I'm using latest PPSSPP build v0.9.9.1-155-gc5e80d0 for Windows.
The emulator load unicode iso files just fine within its internal select file dialog.
But it fails to load the game from from the command line.
I wonder if PPSSPP support WideString parameters in the command line ?

Other emulators load Unicode filenames just fine so, I know it's not my frontend causing this. Also, other PSP games with ANSI filenames load OK from command line in PPSSPP

Code:

"D:\emulators\PSP\ppsspp\PPSSPPWindows64.exe" "D:\emulators\PSP\games\究極魔界ゴブリン.iso" --escapeexitsemu

Thank you.
