Simpler way to set fonts/set default encoding to Unicode/IDENTITY-H for PDFs?

[Paul Pop]

Hello, do you know of any simple approach to set the default text encoding to Unicode for the iText PDF renderer other than adding an external font with the IDENTITY_H option in `.addFont(...)`? Docs reference for the current approach: The Flying Saucer User's Guide

I also tried adding multiple fonts at once via `renderer.getFontResolver.addFontDirectory`. However, when the PDF is generated, the encoding used is still the default one, ANSI/Latin-1, even if the font files would support Unicode, and the method has no parameter to set the encoding.

I'm thinking to contribute a PR to have an overloaded `addFontDirectory` where the encoding can be specified (or maybe we can even have Unicode set for the renderer by default?). The one that is called now I see then calls `addFont` with `Cp1252` as encoding.

PS: @Andrei / @Peter, this project has been very useful to me. If you have some crypto wallet(s) for the project, I'll happily chip in the price of a coffee :)

Also, is it okay to reuse an ITextRenderer? If I generate multiple PDFs from (different) HTML, how should I clean up the renderer's document between successive runs (also to save memory)?

Thanks.

Hi Paul!

1. For adding a single font with a specific encoding, there is a method:

public void addFont(String path, String encoding, boolean embedded)

public void addFont(String path, String encoding, boolean embedded, @Nullable String pathToPFB)

2. For adding multiple fonts, I've added method with "encoding" parameter:

public void addFontDirectory(String dir, boolean embedded)

public void addFontDirectory(String dir, String encoding, boolean embedded)

It's only in the "main" branch for now. Not released yet.

3. About reusing ITextRenderer instance - I don't know the right answer, but in our projects, we always create a new instance of ITextRenderer for every new PDF.

P.S. I have zero knowledge about crypto wallets. I am too old for this shit. :)

Hi Paul!

FlyingSaucer 9.10.2 has been released.

You can use the new method addFontDirectory(String dir, String encoding, boolean embedded).
