You are using DaDaBIK version 8.3 Enterprise
PHP Version: 7.1.6
sqlite version: 3.8.5
Web server: Apache

Hello,

I've just upgraded from version 8.1 to version 8.3 given that the "pdf export" is something that we need on regular basis. The pdf export is working fine (default template/no template), however the output PDF shows "?" characters instead of some UTF-8 characters that were supposed to be in the text eg. (čćž,...).

I've tried importing some UTF-8 fonts in the font folder of tcpdf and tried to set new UTF-8 font in "pdf_functions.php" file, but the result is still the same (just in case if the default font is not a UTF-8 font).

How can I set the pdf export to include correct UTF-8 characters in exported PDF?


Regards
Miro

Hello,
one solution is to use a font that is able to display all the utf8 characters (the core TCPDF font used by default is not), for example freesans:

1) Download the entire TCPDF library from here: https://github.com/tecnickcom/tcpdf

2) Unzip it and look into the fonts folder

3) copy all the files related to freesans (freesans.ctg, freesans, freesansb.ctg, ....) in the include/tcpdf/fonts folder of your DaDaBIK app

4) change the font used by the default PDF template from the templates/default_header_no_template.html file changing:

font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen", "Ubuntu", "Cantarell", "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif;

to:

font-family: "freesans", -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen", "Ubuntu", "Cantarell", "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif;

This should fix your issue.

Let me know.

Best,

Hello,

i've done the procedure on your instructions and it works great (in my previous attempt i didn't copy all the definition files from font folder, only the font php file).


Thanks Eugenio.
