4326	Property tree json reader and writer aren't standards-compliant	Leon Mergen <leon@…>	Sebastian Redl	"According to the json standard, the ""/"" character should be escaped to ""\/"". The boost property tree Json parser generates an error when such an escape sequence is encountered on input, and doesn't properly escape it on output.


Here is a patch for the two files based on the 1.43 tree:
