Regex \s doesn't match zero width space Topic is solved

[eugenesv]

this fails (there is a space in the first string u200B though maybe the paste/forum ate it)

Code: Select all

msgbox(RegExReplace('​','\s','1')='1')

Usually \s is defined to match a space, tab, newline, carriage return, or vertical tab. Zero-width space is not among those. Testing in regex101.com \s also doesn't match it, whereas \p{Cf} does. Why do you think it should match it?

[eugenesv]

I thought it should match since it's called a space :)

But you're right, it's not even defined as whitespace propertied char in Unicode, so not really an AHK bug, just a Unicode complexity, sorry about the false alarm, will use the more extensive matching rules
