Hello,
There is a misunderstanding somewhere because on HikaShop's side the twitter/X logo is a PNG, therefore an image.
From there, we no longer understand what to talk to you about regarding the font problem.
So, can you provide us with specific information on the context in which this Twitter logo appears?
The ideal would be to have an URL link so that we can see the context, or failing that a screenshot with a description of what we see, email, invoice, product listing etc...
Awaiting your returns
Regards
