Font error - MalgunGothicReqular -

Hello Kimyy,

We're sorry for the trouble you had, please navigate to Adobe Reader's Preferences from Edit>Preferences>Page Display and under Rendering select 'user Local fonts', Click OK, close the PDF and Adobe Reader, launch Adobe Reader and PDF and check.

Also, check for the latest update of Adobe Reader from help>check for updates, reboot the machine after updating Adobe Reader.

If the issue persists, the issue could be that the fonts are not embedded in the PDF file. You may have to contact the creator of the PDF file and have to ask them to embed the fonts in the PDF.
