Problem with superscript

Sure! In this example I copied ¹²⁵I and it changed to just 125I.

But my problem is not so much that it changed in the Search field, but that the search function makes a difference between superscript and non-superscript characters. Our customers would try to search for 125I, but will then not find the things we are looking for if we use the correct text format (¹²⁵I). For now I have just changed to the incorrect format (without superscript) so that people will find the right pages, but it makes the texts look quite unprofessional.

Note: 125I is just an example. We have many more in the same format.

Yes, I have had to change all superscript text to regular text on all our pages so that they searchable. This is NOT how I want it to be. I hope that you manage to sort this out because our texts look unprofessional now because all our readers know that this is not how it is supposed to look.

Sure. I made an example here:
https://ligandtracer.com/benefit-of-later-time-point-pet-imaging-of-her3-expression-using-optimized-radiocobalt-labeled-affibody-molecules-2020/

If you search you will not find the page, because it is written as ⁵⁷Co.

Ok, I wasn´t aware that the synonym function existed. Unfortunately, it doesn´t work. I tested it on staging2.ligandtracer.com (where I haven´t changed all the superscripts to normal text) and it still doesn´t find the right pages when searching.
