Special Characters Not Working in UE Editor

Hello. Hoping someone can help or has encountered this before. I am trying to copy special characters into unreal engine and whenever I type the Tlingit words that use the latin k and g keys with underline, they show up in unreal engine as symbols.

I have tried the google sheets trick and that gets the accents to work for above the words. I have tried saving as unicode UTF16 in notepad and saving as csv as well and am running into the same issue. Please advise on best route to get these special characters in my project as I am currently not finding a way to do it without the data populating these icons. My entire project is built around this language so I can’t necessarily omit these words. Have also tried saving it in just about every csv option available to me so I am thinking it has to do with the UE editor itself at this point.

Here are some example words if it helps you recreate the issue.

Hi, did you ever solve this? I am having a similar issue.
