toPDF export wrong behavior

When I try to export a datatable to a pdf file, using toPDF I get strange behavior for example the word
TELEGRAM appears in the generated pdf as “TE3EJ Raw”, but if I copy the word from the pdf and paste it into notepad, it appears correctly, I don’t understand anything, this happens from the second line of the datatable exported in the pdf, even if I order for certain fields the pdf is created well. What is happening to me? , I have tried to change the url to a different .tff file than the one that exists by default but I am not successful

Thanks in advance
