Bug Description

Characters such as $ seem to ignored in fixed strings mode.

Relevant Screenshot

No response

To Reproduce

I have some sample input text:

Recall that we defined the sum of two elements of 𝐅𝑛 to be the element of 𝐅𝑛 obtained by adding corresponding coordinates; see 1.13. As we will now see, addition has a simple geometric interpretation in the special case of 𝐑2.

I enter the following search and replace (with fixed strings enabled):

Search: 𝐅𝑛
Replace: $F^n$

And I get the following output:

Recall that we defined the sum of two elements of ^n$ to be the element of ^n$ obtained by adding corresponding coordinates; see 1.13. As we will now see, addition has a simple geometric interpretation in the special case of 𝐑2.

Even though fixed strings are enabled, the characters $F seem to be dropped.

I tried setting autoBraceSimpleCaptureGroups=false but that seemed to have no impact.
