Subject: [PATCH] Strip private area unicode characters from signs
|
|
|
|
It is not immediately clear how these characters ended up on signs in
|
|
previous versions. It is clear, however, that they now render as empty
|
|
unicode boxes in 1.13, whereas previously they rendered as invisible
|
|
characters.
|
|
|
|
When these signs are loaded in versions after this commit, these
|
|
characters from the private use area of the Unicode block will be
|
|
stripped. The sign will then be marked to ensure this conversion only
|
|
runs once.
|
|
|
|
There is a flag -DPaper.keepInvalidUnicode=true that can be used if you
|
|
do not want us to strip these characters from your signs, though I can
|
|
think of no reason to use it.
|
|
|
|
Fixes GH-1571
