Using formatting codes on the letter "y" while naming an item does not work.

Whenever I type the letter "y" with a formatting code when naming an item, it changes the whole name including the "§" symbols to #'s. This does not happen when the "y" symbol does not have a formatting code attached to it.

Steps to Reproduce:

1. Place an anvil

2. Interact with the anvil

3. Name the item something with the letter "y" in it

4. Format the letter "y"

5. Type the rest of the name

6. Remove the output item

7. The item name including the section sign (§) is all hashtags
