The PDF event timetable does not render CJK characters correctly

[tomasr8]

Copied from the forum so it does not get lost.

... the PDF view of the schedule is not showing the Japanese characters properly.

Possible solutions:

• Add a fallback font for reportlab: https://stackoverflow.com/a/35371704/3911147
• Use weasyprint (what we use for document templates) to generate the timetable, assuming it can handle CJK characters

Can we try the receipt generation with CJK chars to see if wasyprint supports it? If we moved this thing to weasyprint we'd probably be able to get rid of a very nice chunk of extremely legacy code ;)

I think weasyprint doesn't support CJK characters.
Sample script(ensure weasyprint is installed)

from weasyprint import HTML

HTML(string="<p>1101号室/Room 1101, 長崎国際大学１号館/NIU Building 1<p>").write_pdf('output.pdf')

Generated PDF:

@hitenvidhani I think this may be a matter of configuration / font selection...

Sorry about that, I have verified that CJK chars are working in receipt generation, so yes weasyprint supports it

Notice the name at the end in the receipt and the same name in the timetable(CJK chars printed as box)

Just to give an update, I started working on converting the timeteable generation to weasyprint a while ago and I have a working POC. I'm hoping to get it PR-ready in the coming weeks
