The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/11/functions-matching.html Description: On https://www.postgresql.org/docs/11/functions-matching.html paragraph 9.7.3.2. Bracket Expressions says "Standard character class names are: alnum, alpha, blank, cntrl, digit, graph, lower, print, punct, space, upper, xdigit". The class "ascii" exists, but is not mentioned (probably a combination of some of the other classes). Are there any other classes? Do they work only for ASCII characters (e.g. '\u00A0' is not picked up by '[:blank:]')? best regards geert
