After creating dupes with French names, I noticed that E accent aigu was showing up in a different font while dupe names were displayed on the UI. It appears appropriately in menu font.
The game did not support alt-code for the characters, and I had to copy-and-paste them into their names.
Steps to Reproduce
Copy an accented character outside of the game, change a dupe's name, and paste the character in.
This issue has been fixed in either a future version or updated in a previous version.
