Hello. Previously, pdftools encoded the hieroglyphs in this format <U+52D9>, and now like this 零. How can I go back to the first format?

R version 3.4.4 (2018-03-15)
Pdftools 1.8,

now:
Ubuntu 18.04.2 LTS

I think the difference is in your locale, not the version of pdftools. R automatically escapes non-ascii strings when you are in C locale.

 txt <- pdf_text(path)
 print(txt[2)

And now try this:

Sys.setlocale(locale = "C")
print(txt[2)

However I would not recommend this. If you really want to get escape sequences you could use stringi:

stringi::stri_escape_unicode(x[2])

That should properly escape utf-8 characters on any locale.
