Text being automatically converted to symbols

I just checked on my website on mobile, and found my heading with the word “travel” displays as an airplane symbol??? Similarly, a heading with the word “research” displays as “re”, followed by the magnifying glass symbol. I can’t find any setting that can revert this. The desktop version as well as the editor displays the headings normally, but when I check the site on my phone it displays the headings as previously described. Pic related

This exactly happens to me aswell and I noticed that I am using that same font. What is the solution?
