[Escalated to WPML Developers team] Strings with HTML entities from Twig template are not showing on website

Hello,

- I have a website with the latest version of WordPress.
- A custom theme used there which contains TWIG files.
- I am localizing the website using latest version of WPML.

My procedure to localize the TWIG content is as follows:
1. I have converted all strings in TWIG files into constants, such as:
title: __('Bezpečné transakční zprávy', 'twigcon'),
desc: __('Posílejte zabezpečené transakční e‑maily, zprávy SMS, PUSH oznámení, nebo třeba dopisy.', 'twigcon')|raw,
etc.

2. To show the strings in WPML, I go to WPML/String Translation and enable the "Look for strings while pages are rendered" option.
3. I render the pages, go back to the settings and export the discovered strings to a .po file.
4. I translate the .po file and import it back with new translations. The translations are successfully visible in WPML under the correct domain (twigcon in my case).

The problem:
When I load the website, some strings on the page appear translated and some remain in the original language. I have noticed that the problem is with strings that contain HTML entities.

When a constant in TWIG file contains a HTML entity, such as non-breaking hyphen (‑), non-breaking space, etc. WPML does not display its translation on the website, even though it exists in WPML database.

I have tried applying raw or escape_html filters to constants in TWIG files, but the results were the same. Nevertheless, if I delete the problematic string, rescan the website, and add the translation for that string manually from within WPML, it shows on the website correctly.

Can you please advise on how to make this work without any workarounds? I.e., export/import.

Can you also confirm that this is the correct procedure to localize the strings from the TWIG files?
