I'm looking at a longer ICU regular expression that contains:
[\\-\\s]
The limits of my understanding is the brackets and the "-", so I'm thinking it means:
match a character, in the range of literal-backslash to any-whitespace...
But how do you do that? Shouldn't a range be two distinct points in the character space, like the classic "[a-z]" ?
If it helps:
The "\s" is "Match a white space character. White space is defined as [\t\n\f\r\p{Z}].
