I don't know about the relative market needs. I think supplementary
character support is important because these characters are part of
Unicode just as much as BMP characters are,
And don't forget, many people think some of the BMP characters are not
important for their software. And that is probably the exact reason why MES-1, MES-2
and MES-3 got created. For Front-End software, it is quite difficult, or I
should say impossible to support even the whole BMP. I crrently see NO front-end
software 100% support the whole Unicode BMP correctly from input to
rendering. Name me one and I can tell you what they didn't do.
For back end software which do pure data process without keyboard input or
text rendering, it is eaiser to implement the whole Unicode BMP range or even
with the surrogate.
and implementing UTF-8
support for the entire Unicode code space is about 0.1% harder than
artificially crippling it by restricting it to the BMP.
Disagree about what you said "about 0.1 % harder".
For many developers, adding 4 bytes UTF-8 to surrogate support simply mean
open a can of worm. After that, they need to worry about how to support
surrogate, which is quite complex in the api design/change. The work to make the
converter convert UTF-8 to a surrogate pair and back is probably as you said "0.1
harder". But work AFTER they open such door is much harder to manage. As the
famouse saying "Unicode is not the answer for Internationalization, Unicode is
the question for the Internationalization". Thanks for all the job opportunity
Unicode standard created (and keep creating) of us :)
