Chinese Fonts on the Raspberry Pi 3

@bask185 Do you have this problem when running your app in PIXEL?
Yes, and because of some slowness bug I have to boot to Pixel. When I boot to the CLI the app runs significantly slower for some reason.

@bask185 I guess if you boot to CLI you get framebuffer device without any hardware acceleration. In this case it is not a bug.
@jsulm That the cause of something might have a perfectly clear reason, does not mean that something isn't a bug persé. That slow running bug was one helluva annoying bug to me, whatever the reason may be.
But how does this help me teach the Raspberry speak Chinese?

It does not, I just wanted to say that framebuffer devices do not have hardware acceleration and this can be the reason for slow UI.

Well I narrowed down the folder out of which the application picks it's fonts. If I leave 1 font, she will pick that one. So I could modify the font in the application.
/usr/local/qt5pi/lib/fontsI vaguely remembered I once had no texts at all, so I dug up some e-mails and I remembered I had to manually copy paste fonts into the folder. What I however don't know is how the app picks one of them. I know it does not pick the first on the list.
www.qtrpi.com's FAQ had a step with which I had to add an export line to .basrc. I think that that line was supposed to copy ttf files to that folder. But that did not work for me.
I already downloaded a chinese font, but now everything were squares.
I now only have to find and copy a complete .ttf file in that folder, that ought to teach this Raspberry some Chinese...

Well I finally have me some Chinese characters, it was indeed copying a suitable .ttf to the fonts folder. I still dont have Thai though :D
I just found a website with which you can open .ttf files so you can look for your unicodes/characters. I only wish I would have thought of this earlier.. like before I solved the file. I still don't know if Qt can work with 2 or more different font files.... all the plain text is kinda ugly now :D

Hi
Qt can use any font installed on the system.
You can even use custom fonts not installed with
QFontDatabase::addApplicationFont("qrc:///resources/Triforce.ttf");

Yeah I came across the QFontDatabase in my 'Quest' for the solution. But not long after, I knew which folder my app was using for fonts. At that point I only had to find a decent Chinese and Thai font.
For me it does not really matter whether the app picks a font out of the resource folder or the "/usr/local/qt5pi/lib/" fonts folder. Well that is not true, it does matter because now I do not have to learn how QFontDatabase works and produce (redundant) lines of code :P + if I want to add a new .ttf, I merely have to download and move the file to the folder. If I would use the resource folder instead I would also have to add a line of code in the app to include that font.
My project is almost done now. So I will update my report and clone the Pi's SD card. My superior was impressed ;)
