Hello @lunacer,
Thank you for reaching out,
Three things can affect it:
1. Check the translation of those texts.
Open the translation files and ensure that the   is not in the translation files. Or use these plugins to solve it by changing the text:
https://wordpress.org/plugins/say-what/
https://wordpress.org/plugins/string-locator/
This is for when you have translation purposes.
2. It can be a plugin conflict:
Deactivate all plugins temporarily. If the problem disappears, it indicates a conflict with a specific plugin. Reactivate plugins one by one to identify the culprit.
3. Update the .htaccess file configuration:
In some cases, specific rules in your .htaccess file might interfere with character encoding. You can check for any rules related to AddDefaultCharset or mod_headers. If you’re unsure about modifying .htaccess, it’s best to consult your host provider.
AddDefaultCharset utf-8
Please recheck your issue and keep us posted.
I hope it helps.
Best Regards
Thank you so much for your help.
I solved the issue with the plugin “Say What?” by adding two conditions that replace “ ” and “갇” with \00a0.
Thanks again, have a good day.
You’re welcome.
I’m glad we could help.
Have a wonderful day.
