Portion of diff was dropped in the mappings update commit. Also remove the option to remove invalid statistics. The server will automatically do this now as of... 1.13?, our option wasn't even doing anything.

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
