Mr. Philip Hazel, Yesterday I created a PCRE regex.
Id
RegEx Replace 59 (?=.+(\x{00F6})){1}(?=.+(\x{00E4})){1}(?=.+(\x{00E7})){1} $1
$2 $3
that matches the string, DAS tausendschöne Jungfräulein ausendschçne 4
times at byte position (14,16],(25,27] and (42,44). Is it good programming
practice to use PCRE regex's such as
'(?=.+(\x{00F6})){1}(?=.+(\x{00E4})){1}(?=.+(\x{00E7})){1}'. Thank you for
your help.
