Depends how much one needs a regex that works for all cases or if
something more relaxed can do the job at hand. I was also thinking that
depending on the particular use case it might be possible to have
a script create the regex and initialize a variable/register and use its
contents in interactive commands to simulate a [:CJK:] character class
more conveniently.

I don't use Perl but I would have expected it to provide native support
for Unicode blocks. In this instance '\p{InCJk_Unified_Ideographs},
which corresponds precisely to U+4E00...U+9FFF.

See this:

Sorry.. in fact, correct was the wrong word.. I really meant something
like 'effectively assigned'.. \u9fbb-\u9fff do belong to the unicode
range but afaict no characters have been assigned. Which makes it
impossible to refer to them by character.. only by code point.
