Character classes don't work for me in v. 7.5.7

[Meir Goldenberg]

The search [[:space:]] does not produce any results in notepad++ v. 7.5.7 on the computer at work (though it works on my laptop). I did check the regular expression checkbox. What could cause this?

@Meir-Goldenberg

it would be interesting to know what you are trying to search, and where you search for it. (code example)

notepad 7.5.7 should find every single white-space (space, tab, cr, lf, ff, vt) if you do a regex search for [[:space:]]

does a regex search for \s work for you ?
(this is an alternative, shorter, writing syntax for [[:space:]])
