Eli.  Could we have a list of Unicode Black Names, so one could do

C-x 8 RET BLOCK-NAME TAB TAB M-<DOWN>

In the last few years, there have been many users who would like to 
easily insert UTF8 characters, even though this has not been very
well received by some developers who have been in the field for a long
time (e.g. regarding Emojis where some prefer text-based communication).

For people in mathematics like myself, easily inserting UTF8 characters
would be considered a valuable innovation.
