exporting s-note files to pdf makes some letters blank

[Shakalen]

Hi!
I have a problem with s-note, which makes the swedish letters "???" disappear when converting the file to .pdf.

I use the "lasso function" in s-note to transform handwritten text to normal text and then when I open the file in adobe reader the letters are gone.

Does anyone know how to fix this?

The only issue I saw is when viewing the exported pdf file, the writing appears to be very jittery. But it turned out to be pdf reader issue. Polaris exhibits that issue. I don't see the jittery in other pdf reader.
