The bug
The tab character U+0009 most often appears as a large space, often the width of four U+0020 spaces. However, in Minecraft, it appears as a control character.
How to reproduce
For some reason this character cannot be pasted into the game at all, so we will need to force it to appear using a command:
/tellraw @p {"text": "a\u0009b"}
Expected results
A large gap between a and b.
Actual results
It appears like a control character.
Can confirm.
