Re: [xsl] JSON to XML using XSLT 3.0 representation

["Martynas Jusevičius martynas@xxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi,

sure enough I hit one of the 0.1% cases in the conversion :) Namely
the form feed char being present in the JSON which produced form feed
in the XML output which is not well-formed XML 1.0.

I've released JSON2XML version 1.0.5 which attempts to address this
issue by doing the default replacement of invalid characters to the
REPLACEMENT CHARACTER (xFFFD), as specified by the json-to-xml()
function.

Could you please take a look at the replacement code (copy-pasted from
StackOverflow :)) - does it look reasonable?
