Do you have custom CSS or a custom list pdf template which is loading your font?

 

[bluetoothbj]

Yes. I have custom CSS and custom list/detail pdf template which loading Chinese font.

Try with Fabrik's PDF debug enabled and check if all is loaded correctly.

And try with php8.2

JS shouldn't matter for PDF.
Check in the browser if the CSS is loaded correctly.
I don't think F4 and domPDF are php8.3 ready.
You may turn J! error reporting on, Fabrik PDF debug off and see if there are any errors/warnings etc in the PDF file (open with e.g. notepad++)

Do you have a link to your list?

Thanks troester,
There are errors when turn J! error reporting on, Fabrik PDF debug off:

Those are solely deprecated messages. Turn Joomla error reporting to None and see if the pdf gets generated.

It takes 30 minutes to generate a pdf which Chinese characters is ???

Downloading e.g. Noto Sans TC into my J! root and adding

...
echo <<<EOT
    @font-face {
        font-family: 'Noto Sans TC';
       font-weight: normal;
                font-style: normal;
                font-variant: normal;
        src: url('http://localhost/j4h40/NotoSansTC-Regular.ttf') format('truetype');
    }
* {font-family: 'Noto Sans TC', sans-serif;}
...

to template_css.php in the PDF template is working fine with Chinese characters

 

[bluetoothbj]

Thanks for your help.
Now solved. I changed to mpdf,and Modify ConfigVariables.php under mpdf/src/Config:

'autoScriptToLang' => true,

'autoLangToFont' => true,

(Default is false)

So mpdf support Chinese characters.

 

[troester]

Glad you got it working.
Keep in mind that you have to do these changes after every Fabrik installation/update.

But it's also working with domPDF.

(I added the Chinese characters to the thread title).
