Glenn Adams commented on FOP-1969:

| If I understand correctly the semantic of elide controls you want something 
like this:
| characters: \u1f468\u1f469\u1f466
| glyphs: 1643
| association: [0, 3]

elideControls() does not change the original characters array, it only removes 
(elides) glyphs associated with elidable control characters in the original 
characters array;

you need to step through the code in elideControls in an IDE in order to find 
why it isn't inserting the non-elided glyphs

> 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;
