Hmm, I almost always refer to
https://github.com/ruby/ruby/blob/trunk/doc/re.rdoc for the regex doc
and therein it's pretty accurate:

[...]
* /\d/ - A digit character ([0-9])
[...]
For instance, /\d/ matches only the ASCII decimal digits (0-9); whereas
/[[:digit:]]/ matches any character in the Unicode Nd category
[...]

HTH,
