translation Problem ,

The thread you refer to has a link to an outdated version of the mpdf extension. 2.3.0 is currently the latest version and can be downloaded here:
woocommerce-pdf-ips-mpdf.2.3.0.zip

For an overview of all versions (including the ones with CJK = Chinese, Japanese & Korean support), you can go to the releases page: https://github.com/wpovernight/woocommerce-pdf-ips-mpdf/releases

Note that because this is a plugin that is not hosted on www.remarpro.com, you will not automatically receive plugin updates, and we can only provide limited support.

That said, could you check to see if updating to the latest version resolves the issue with the squares?

The strings in the totals that are not translated are from WooCommerce directly (rather than from PDF Invoices). What’s your site language? Are these totals translated in the WooCommerce emails your site sends out?

Hello
Thanks for your help and support

i have update to the latest version of woocommerce-pdf-ips-mpdf.2.3.0

my website language is Arabic
the problem of the strings solved

but the problem of the product name not solved

this after the update

What does that look like in HTML mode (adding &output=html to the URL of the PDF)? Are those Arabic characters? Is it possible that a different font is being applied to those links?

Yes it’s URL in Product Name

the problem in URL Text , it’s the same like product name

but in URL not success to capture the correct text

Are you saying the words are the same – it’s just the product name repeated again as a link? There are more square characters (after “[“) that are not a link. Is it possible that a different font is applied to this? If you are a web developer you could go to HTML output, then do right click on the text that is not appearing correctly in the PDF to do “Inspect Element” and check the font that is assigned.

yes as you say correctly

it’s just the product name repeated again as a link? There are more square characters

i’m not a web developer

tell me how can i go to HTML output to inspect it ?

HTML mode I described in my previous post.

For inspecting the element:

1. add &output=html to the URL of the PDF, reload the page
2. Right click on the text that wasn’t working before (in HTML mode it will probably show fine)
3. Click “Inspect” (make sure to click precisely on the text!)
4. There will be an area with a tab “Styles” selected (or “Rules” in Firefox”), you could check if there’s a font-family there, but it’s even better if you switch to the “Computed” tab, and then enter ‘font’ into the Filter search box.

Please share a screenshot of what you see there.

Thanks for your care
after i enable &output=html

i have follow this topic
https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/using-custom-fonts/

Aha, that makes sense then. You can’t use Google fonts in mpdf, so it can’t find the font. If you remove the font declaration there, it will probably show correctly. Or add a custom font following instructions I posted in your other topic.

The documentation link you posted above is not applicable to mpdf.

no i host the google font in my server like your instructions
