Most Unicode characters have full names, for example is "RIGHT DOUBLE QUOTATION MARK". You can find a useful reference here, just type in the character you want to find the full name of and look in the DESCRIPTION column.

Your challenge is to write a program or function that outputs itself as a string of these. You can output as an array, or space/newline separated.

Scoring

This challenge is scored in characters instead of bytes - Least characters wins!

You can only use characters with descriptions other than U+(Whatever), so and similar are banned.

External resources are allowed, but those without are generally more interesting.

Raku, 37 characters

Variation of the standard Raku quines using print to avoid the trailing newline and .uninames to convert to a list of character names.

“__import__('unicodedata').name(*'''“ ''')“jⱮṾ;ṪƊŒV€Y”jⱮṾ;ṪƊŒV€Y

Try it online!

-2 bytes by splicing and splatting instead of using string

This still feels... easily outdone. Probably using v.

“...“...“jⱮṾ;ṪƊŒV€Y”              Operate on this list of three strings.
                      Ṿ           Get its string representation
                       ;          and concatenate
                        Ṫ         and pop its last element;
                     Ɱ   Ɗ        for each character of that result
                    j             join the remaining two elements on it.
                          ŒV€     Evaluate each as Python,
                             Y    and join the values on newlines.

In order to place a literal single quote inside the Python code and use it as such, we can't use '\“' because most other characters will either result in an unwanted incorrect escape sequence or an actual backslash and a TypeError, we can't use "“" because now we just have the same problem with double quotes, and we can't use '''“''' because ''''''' parses as '''''' ' resulting in a SyntaxError. '''“ '''[0] only breaks even with the previous version, but fortunately unicodedata.name can take an optional second argument--a default for if the character given does not have a name--so we can use the splat operator * to send the unwanted space there for two less bytes.

    \$\begingroup\$ @Downvoter, a comment would be appreciated. Given that you also (apparently) downvoted Recusrive's solution, I'm guessing you're taking issue with that fact that we're fetching the data from an external resource, in which case your issue should be with the challenge which explicitly allows that, rather than any individual solutions making use of that allowance. Also, fetching them from an external resource is really not that much different from importing them from a built-in library. \$\endgroup\$

    \$\begingroup\$ My answer has just received another downvote. While @user253751 is correct in saying that "those without are generally more interesting", it doesn't make our (mine and Shaggy's) solutions any less valid. IMO only invalid answers should be downvoted. Seeing as a few others (Jelly, Raku) were downvoted, I suspect that the downvoter(s) are downvoting solutions that are not building the unicode names from scratch (tsh's solution, for instance, has not been downvoted). However, ovs's answer, which uses a library (there isn't even any effort to extract text from a source) has not been downvoted. \$\endgroup\$
