Sign text going outside the sign when turning off unicode font after typing maximum letters

Sign text going outside the sign when turning off unicode font after typing maximum letters

What I expected to happen was...:
I typed a sign with maximum letters using unicode font, then I turned unicode font off and expected the sign to be normal

What actually happened was...:
The text of the sign went outside the sign and it looked really wierd

Steps to Reproduce:
1. Turn on unicode font
2. Type something on a sign that reaches the maximum limit for how much you can type
3. Turn off unicode font and look at the sign
