I am using the latest free version for java and when i convert to pdf/a the fonts contained inside the pdf are not replaced correctly and the content is lost. While using online converters i found that they are successfully converted and don't embed the fonts at all (type 3 fonts) and are still valid but using the conversion from spire does not have the same results, the fonts are embeded (or at least attempted to) but the text is unreadable.
Is there any way to convert a pdf with type 3 fonts to pdf/a and mantain the text of the pdf?
Ps. I tried the demo version for the licensed version for spire pdf for java and got the same results.
