  Space in string allowed, but not at first or last position

  Here is my take on the topic:

  if (subject.match(/^(?=\S+)(?=[a-zA-ZàáâäãåèéêëìíîïòóôöõøùúûüÿýñçčšžÀÁÂÄÃÅÈÉÊËÌÍÎÏÒÓÔÖÕØÙÚÛÜŸÝÑßÇŒÆČŠŽ∂ð ,.'-]*$).*(?=\S).$/)) < // Successful match >

  It basically says, start with at least something which isn't a space. So here goes conditions 1 and 5.

  Then make sure that the whole thing consists of only allowed characters. Here goes all your other conditions.

  Then make sure that there is at least a non space character, match it and then match tne end.

  More details:

  " ^ # Assert position at the beginning of the string (?= # Assert that the regex below can be matched, starting at this position (positive lookahead) \S # Match a single character that is a “non-whitespace character” + # Between one and unlimited times, as many times as possible, giving back as needed (greedy) ) (?= # Assert that the regex below can be matched, starting at this position (positive lookahead) [a-zA-ZàáâäãåèéêëìíîïòóôöõøùúûüÿýñçčšžÀÁÂÄÃÅÈÉÊËÌÍÎÏÒÓÔÖÕØÙÚÛÜŸÝÑßÇŒÆČŠŽ∂ð ,.'-] # Match a single character present in the list below # A character in the range between “a” and “z” # A character in the range between “A” and “Z” # One of the characters “àáâäãåèéêëìíîïòóôöõøùúûüÿýñçcšžÀÁÂÄÃÅÈÉÊËÌÍÎÏÒÓÔÖÕØÙÚÛÜŸÝÑßÇŒÆCŠŽ?ð ,.” # The character “'” # The character “-” * # Between zero and unlimited times, as many times as possible, giving back as needed (greedy) $ # Assert position at the end of the string (or before the line break at the end of the string, if any) ) . # Match any single character that is not a line break character * # Between zero and unlimited times, as many times as possible, giving back as needed (greedy) (?= # Assert that the regex below can be matched, starting at this position (positive lookahead) \S # Match a single character that is a “non-whitespace character” ) . # Match any single character that is not a line break character $ # Assert position at the end of the string (or before the line break at the end of the string, if any) " 

  You need to use the RegExp ^ and $ codes, which specify the start and ending respectively.

  See more documentation about this.

  ^(?! )[a-zA-ZàáâäãåèéêëìíîïòóôöõøùúûüÿýñçčšžÀÁÂÄÃÅÈÉÊËÌÍÎÏÒÓÔÖÕØÙÚÛÜŸÝÑßÇŒÆČŠŽ∂ð ,.'-]*[a-zA-ZàáâäãåèéêëìíîïòóôöõøùúûüÿýñçčšžÀÁÂÄÃÅÈÉÊËÌÍÎÏÒÓÔÖÕØÙÚÛÜŸÝÑßÇŒÆČŠŽ∂ð,.'-]$ 

  ^ anchors the pattern to the start of the string

  $ anchors the pattern to the end of the string

  (?! ) is a negative lookahead that ensures, that its not starting with a space

  Then there follows your character class with a * quantifier, means 0 or more times. At last there is your class once more, but without space , this is to ensure that it does not end with space.

  Its a pity that Javascript regexes doesn't have Unicode support, and does not allow \p for all kind of letters.

  Regex - How to extract all words of a camel cased string, Assume I have a string that consists of multiple words.
