Describe the bug
Chevin font corrupts text copy pasted from PDF.

To Reproduce

const Test = () => (
  <Document>
    <Page>
      <View>
        <Text style={styles.roboto}>
          The Portable Document Format (PDF) (redundantly: PDF format) is a file format developed by Adobe in the 1990s to present documents, 
          including text formatting and images, in a manner independent of application software, hardware, and operating systems.[2][3] 
          Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the 
          text, fonts, vector graphics, raster images and other information needed to display it. PDF was standardized as an open format, 
          ISO 32000, in 2008, and no longer requires any royalties for its implementation.

Expected behavior
Text copy pasted from PDF from Chevin font paragraph should equal the Roboto version:

The Portable Document Format (PDF) (redundantly: PDF format) is a file
format developed by Adobe in the 1990s to present documents, including
text formatting and images, in a manner independent of application software,
hardware, and operating systems.[2][3] Based on the PostScript language,
each PDF file encapsulates a complete description of a fixed-layout flat doc-
ument, including the text, fonts, vector graphics, raster images and other in-
formation needed to display it. PDF was standardized as an open format, ISO
32000, in 2008, and no longer requires any royalties for its implementation.

Actual behavior
Copy pasted text from PDF from Chevin paragraph is corrupted:

The Portable Document Format (PDF) (redundantly: PDF format) is a vle format depeloAed 
by 1dobe in the 900,s to Aresent documentsg includinx tewt formattinx and imaxesg in a

Having the same issue, I need to parse the document after it is created to identify headers and generate Table of Contents. Any solution to this? FIY it happens with every font, I've tried Atlas Grotesk, OpenSans and Arial, all with the same issue.

[diegomura]

Not sure why some fonts are not loaded correctly by fontkit. Something that worked for me is opening the font with a font editor (such as birdfont) and export it again without changes

[Droow]

I just discovered that if I use one of the "default" fonts (Helvetica to be exact) then it works. This is then the output from pdffonts command:

So I think it is the Identity-H encoding doing this mess.

EDIT: I just tried new font (Cocogoose Pro) and it works like a charm! Even if it has Identity-H encoding, so I guess it was a cmap what was wrong.

Exporting font with Birdfont fixed the problem on Chevin. I had tried to do the same fix with FontForge font editor but with no luck this time.

I had the same problem with react-pdf 1.4.3 but then exporting the font again with FontForge fixed it. Strange that different re-export tricks are needed for different versions of this library.

Having the same issue using Source Han Sans.

+1 I had this problem with IBM Plex Sans but using Birdfont to re-export my TTF files did the trick.

If someone else is using google fonts I also managed to fix the fonts using fontforge with the following command

fontforge -lang=ff -c 'Open($1); Generate($2); Close();' xxx.ttf yyy.ttf
