Comment (by Ilya Bobyr <ilya.bobyr@…>):

 While it is true, that char can not handle whole Unicode, it can still
 handle values larger than 0x7F if you view it as an unsigned integer.
 There was a fix for JSON writer in version 1.45 that makes it
 unconditionally view character type as unsigned thus allowing it to save
 UTF-8 encoded strings even if char is signed.
 Here is a similar patch for the JSON reader.  While it still has
 std::min() in there it uses maximum value for unsigned char when clamping
 a character value been read.

 This way JSON writer and JSON reader are doing the same kind of
 transformation to the characters and UTF-8 encoded strings can go through
 a full save/load cycle.
