> 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
> 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;

> Glyphs should be rendered
