treated as single unicode codepoint for display purposes)

> Platform: All

> testing.xml, testing.xsl, tiffttc.zip
> unicode codepoints outside of the BMP (base multilingual plane), i.e., whose 
> scalar value is greater than 0xFFFF (65535), are coded as UTF-16 surrogate 
> pairs in Java strings, which pair should be treated as a single codepoint for 
> the purpose of mapping to a glyph in a font (that supports extra-BMP 
> mappings);
> at present, FOP does not correctly handle this case in simple (non complex 
> script) rendering paths;
> furthermore, though some support has been added to handle this in the complex 
> script rendering path, it has not yet been tested, so is not necessarily 
> working there either;
> fop test.fo -c fop.xconf out.pdf
> Glyphs should be rendered
