Bug of the week

Bug 18927 - revXMLSetAttribute with diacritics or Unicode characters breaks the XML tree instead of throwing an error

When LiveCode gained general support for Unicode strings, many of the external APIs didn’t get updated to transparently support Unicode, including revXML.

The reporter of this bug provided an extremely effective and well-explained demonstration of some of the problems this causes.

Currently, strings passed to some revXML handlers, including revXMLSetAttribute, may need to be pre-encoded to UTF-8 using the textEncode() function.

Help needed!
