Signs with some special (possibly corrupted) characters on them will cause the client to freeze and possibly crash.
For example, if the data `CgpQCqA35sI=` (base64-encoded because it contains non-printable characters) appears in a sign's `Text` NBT tag, the client will freeze and be unable to do anything except moving around.
This bug was discovered on a world created by a third party server.
