The font in the attachment is not the same as the PDF in the browser
Some fonts have a problem with character spacing
Is the font renamed to "basic.ttf" to match the src in the @font-face rule?
The names are consistent when generated
Can you attach the PDF that demonstrates the problem?
The difference is the spacing of 013
Prince supports the OpenType GPOS table for kerning, but this font only has the old TrueType kern table, which Prince does not currently support.
So that's it! Thank you for your answer
