Current Behavior

Weird artifacts are showing up in more complex char files.

I believe this is because the character tested has multi-letter variable names rather than the usual single-letter variable names.

Steps To Reproduce

# fox.cow is provided at the bottom of this issue
chara say -f ./fox.cow "Hello world"

Expected Behavior

For there not to be characters (text) in the character.

Other Information

• Tested with fox.cow
