This doesn't work for me. :(

It works to the left of the zwj, such as
=foo=\zwj{}bar

...but not to the right as you did above.

It's hard to read the value I have for org-emphasis-regexp-components
but it looks like } is in there, so I guess it should be working?

No, it is only in the POSTMATCH part. If you add it to the PREMATCH part too, then your example would work.  But I think it would be neater to put a pair of literal "zero width space" characters in your file.  I managed to get this to work by doing: 

(setq org-emphasis-regexp-components '("[:space:][:cntrl:]('\"{}" "[:space:][:cntrl:]-.,:!?;'\")}\\[" "[:space:][:cntrl:]" "." 1))

This means you can write "fuzzy​/wuzzy/​wuzzabear" where there is a 0x200B character (ZERO WIDTH SPACE) either side of /wuzzy/ (hopefully this will survive in the email).  I inserted the characters with "C-x 8 RET ...". 

In case you prefer to have something more visible in the source file, I also made it so you can use any ascii control character to bracket the delimiters.  For instance, the NULL character: "fuzzy^@/wuzzy/address@hidden".  Note that those are not real NULLs, but are how they appear in the emacs buffer.  You can insert them with "C-q 0 RET".
