In R2013b, the restrictions were:
- text() objects such as labels support only some specific named characters such as \Alpha, and this requires the interpreter property to be set to tex or latex
- some text() objects did not have an interpreter property, but in some cases it was possible to find the text() objects and replace them with other text() objects that do support Interpreter
- interpreter latex did not support any character with position more than 255 (and still does not, even in the latest MATLAB versions)
- interpreter tex did not support any character with position more than 255 (but does in R2014b and later)
- uicontrol style text and edit did not support any character with position more than 255 (but does in R2014b and later)
- uicontrol style push, radio, and check supported HTML 2.0 named entities, provided that the 'String' property began with '<html>' (not case sensitive)
- at the moment I have forgotten whether uicontrol style listbox and popup supported HTML 2.0 named entities... I think they did
- uitable data property supported HTML 2.0 named entities, provided that the 'String' property began with '<html>' (not case sensitive)
- Other than as described above, there was no support for character positions 256 and beyond.
R2014b added much more support for characters beyond 255 (... except for latex interpreter.)
