What I expected was: I wanted to write in a book with a pen in colored text and the first thing I did was to put a § sign to format the text
What actually happened: the § sign did not register in the book with a pen
Steps to play:
1. Opened a book with a pen
2. Put a § (Alt + 21) sign to format the text
3. The § will not be written in a book with a pen

Ok
Why haven't you repair it?

Duplicate of MC-1572.
The § symbol is slowly being removed from Minecraft. Use Raw JSON text instead.
