stri_split_regex() - not working for \\p{Z} ?? #327

Closed kbenoit closed 6 years ago

Maybe I'm daft here, but why does the first one not work?

> stringi::stri_split_regex("one\ntwo\tthree", "\\p{Z}+")
[[1]]
[1] "one\ntwo\tthree"

> stringi::stri_split_regex("one\ntwo\tthree", "\\p{WHITE_SPACE}+")
[[1]]
[1] "one"   "two"   "three"

Hi Ken, see Table 12 in http://www.unicode.org/reports/tr44/tr44-21.html
