Anvil changes name to question marks when renaming with Asian characters

This works on any game mode.

Use an Anvil and place an item into it. Rename the item so it uses non-English characters (Asian characters do this consistently). The name will change to question marks anywhere where the characters are used.

On a side note, some accented Latin characters also change to blocks with question marks inside them.

The names do appear for a short time but they quickly disappear.

This may happen on other versions as well.
