title: Regular expression with Unicode Characters
body: <p>I need help with a regular expression, I need to catch the characters , ⚡,❓ and others in a string. If this character is at the beginning of the line and without a space, insert a space on the right, if the character is at the end of the line and without a space in front of it, insert a space on the left. And if the character is in the middle of the line without spaces, insert spaces on the left and right. So far, all I can do is get the character itself '<code>/[\x{000ff}-\x{fffff}]/u</code>'</p>
