Moodle 2.6.2
Certificate type: Letter Embedded
Border Image: Fancy1-black
User sets language to Japanese
Clicks on "Get your certificate"
In the date area of the certificate is a question mark inside a box (see attached snip, couldn't upload the whole file).
I read MDL-40107 and also did the test print which shows the same character (also see attached snip, couldn't upload the whole file).
I upgraded to tfpdf 6.0.065 from 6.0.031 and the test print is the same.
Any thoughts?
Thank you in advance.
