I’m running into problems with matching unicode letters with regexps. It works in a Figwheel browser project I have:

(re-seq #"(?u)[\p{L}]+" "adams-äpple")
=> ("adams" "äpple")
But in shadow-cljs, targeting node, I get this:
(re-seq #"(?u)[\p{L}]+" "adams-äpple")
Error: <eval>:1
cljs.core.re_seq.call(null,/[\p{L}]+/u,"adams-\u00E4pple")
                 ^
SyntaxError: Invalid regular expression: /[\p{L}]+/: Invalid escape

And in the browser console as well as in node this works:

> "adams-äpple".match(/[\p{L}]+/ug);
[ 'adams', 'äpple' ]
