Hi, I'm facing a strange result while trying to scan a string: CL-USER> (defconstant +iso-8601-regex+ "([0-9]+)-([0-9]+)-([0-9]+)[\sT]*([0-9]+):([0-9]+):([0-9]+)[+-]([0-9]+)" ) +ISO-8601-REGEX+ CL-USER> (cl-ppcre:scan-to-strings +iso-8601-regex+ "2006-04-13 00:00:00+00") NIL CL-USER> (cl-ppcre:scan-to-strings +iso-8601-regex+ "2006-04-13T00:00:00+00") "2006-04-13T00:00:00+00" #("2006" "04" "13" "00" "00" "00" "00") For some reasons, \s seems not to match a whitespace character, unless the space within "2006-04-13 00:00:00+00" is not the space cl-ppcre expects (encoding on Linux?! Hmm... a space is more likely to be encoded with 0x20, isn't it?!). I tried to match both "2006-04-13 00:00:00+00" and "2006-04-13T00:00:00+00" with the Regex Coach (on Windows), and it works perfectly with that same regex! Any idea? What can I check?
