Does anyone else have issues with the PDFs for traditional characters? There are just random letters in there, no characters (at least for the level B1 Pre-Intermediate). Would like to book classes there, but can’t check whether it’s worth it or not.

Hi, I’m Ame from Support team. Thank you for raising up the issue in the PDF. I checked again the material and it works fine from my side. Could you please provide some screenshot and also note down the software and the device that you are using? It would be really helpful for me to investigate what’s wrong. My guess is maybe an issue happened in the conversion process or maybe the file is not compatible to some devices. Also I sent you email from support team. Sorry for late reply as I just came back from National Holiday - Lunar New Year in Vietnam.
Also maybe the font was not installed in your computer to read Mandarin Traditional.
We are now using the font name Noto Sans CJK SC Regular and Noto Sans CJK SC Bold. I hope it helps
I would just like to bring this issue up again.
I am using MacOS and can type in 繁體字
I can read traditional characters on websites using Safari.
But the pdfs for the lessons just have random characters
I am still getting the same problem with using my iPad. It is quite annoying because I can’t review the lesson before booking and seeing if it is at the right level.

Can you try to open it in folder of your computer instead of Safari? We also don’t know why sometimes, opening our material on Safari makes the font look weird like that. It just happens with some materials and only with some ios version when opening through web browser, not all, although we use the same font for all our learning materials.
I did some experimenting.
I downloaded the pdf file and opened it with the preview app in MacOS. It gave the strange characters.
Same happens if I open it using Safari
I tried using Chrome and Opera to open the file and those worked! Unfortunately , I don’t like using Chrome at all but Opera is okay.
Have you tried Mozilla? It works for me.
