Khmer fonts again... in pdf this time

[Frederic Muller]

Hi!

Using mPDF to automatically save a php generated page into PDF I am
struggling getting Khmer characters out.

The Khmer display in the web application is fine, no issue there. When
trying to identify which fonts are being used I get this:
-apple-system, system-ui, BlinkMacSystemFont, "Segoe UI", Roboto,
"Helvetica Neue", Arial, sans-serif

Now when trying to use mPDF for this same address I get various
unsatisfying results:
1. Fonts apparently need to be self hosted in a dedicated folder, making
a Google Fonts css call doesn't seem to work
2. Using KhmerOs fonts is the only way I'm getting some Khmer characters
so far. Unfortunately I am also getting empty squares between some of
the khmer letters while I should get nothing. No letter seems to be
missing though
3. Using all other fonts (I'm thinking of Noto Sans but tried Bayon and
others) I only get squares and no Khmer letters at all.
4. And since this is used for the name+address fields in fact I have
some Latin alphabet and Khmer alphabet combined. I haven't managed to
find a font which could display both at the same time. It seems I need
two div with 2 different font specifications.

This is not very Linux oriented but it'd be nice if someone had some
idea or directions.

Thank you very much.

As a last resort/ugly hack if the document is short you could import into Inkscape and then export the SVG as PDF.  Not ideal, I know, but it should work.

Hust as long the font is not embedded Inkscape will not help you either. You have to tell mPDF to embed the font or convert them to paths. Don't ask me for the command ask pdfkungfu @ twitter

Hi!

A bit of follow up: apparently it seems to be an issue with mPDF and
could be that the zero-width space is "printed" as an empty square in
PDF documents they generate. Still working on identifying the issue but
I'm somewhat hopeful we'll resolve the problem soon.

By any chance could someone confirm in the attached image that those
square are zero-width characters?

Thank you.
