[Ernest Yao]

After updating to Calibre v4 (now v4.3.0), converting to PDF always gets error.
Environment: macOS 10.15.1, Calibre 4.3

Here's the error log and I upload the original azw3 as attachment.

[Kovid Goyal (kovid)]

Works fine for me with default options. That error has to do with
subsetting fonts, what fonts are you using? From the log it looks like
Ping Fang and FZYASongs but I get no errors with those either, though I
dont know if they are installed on my macOS machine or itis using a
fallback.

[Kovid Goyal (kovid)]

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

[Ernest Yao (ernestyao)]

Yes, I'm using FZYaSongS-L-GB. It's installed in my macbook. The same options work in latest v3.

I'll try in the next release. Thank you.

fixed in next release.

[Ernest Yao (ernestyao)]

This conversion bug is fixed in v4.6. But I got an error when converting another azw3:

“

  File "site-packages/calibre/ebooks/pdf/html_writer.py", line 1223, in convert
Error: ZLib returned an error.

”

Should I report another bug and close this one?
