Fix null characters in binary plists

[dnicolson]

This prevents null characters from terminating lines when converting binary plist files to XML.

Before:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>nullByte</key>
    <string>text
</dict>
</plist>

After:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>nullByte</key>
    <string>text␀more</string>
</dict>
</plist>

But is it a normal/frequent condition for there to be null characters?

Can you attach me a plist with that problem?

[dnicolson]

Not frequently, but I have encountered control characters in binary plist files, presumably when unfiltered text is stored in string fields. In that instance, it broke some text editors (now fixed) when trying to decode the binary into XML.
