GitHub user jknight opened a pull request:
https://github.com/apache/pdfbox/pull/36
Update PDPageContentStream.java
This function writes bytes as ascii characters directly to the page.
For use cases where only ascii text needs to be written, this solves a few
problems:
1) Avoids the "No glyph for X" issue (eg
https://stackoverflow.com/questions/42228567/remove-illegal-characters-from-string-with-pdfbox).
2) While it's possible to pre-process text before using showText(), this
means the data will be looped through at least twice since PDFont.encode()
loops the text.
3) Preforms better. Everything can be kept as bytes without having to go to
text
Benchmarks vs showText():
2000 page pdf: showText(): 579ms / writeAscii(): 419ms
1000 page pdf: showText(): 283ms / writeAscii(): 193ms
