อักขระ Unicode ทุกตัวเป็นของ "หมวดหมู่ทั่วไป" เพียงรายการเดียว
จากนี้ ตัวที่มีเครื่องหมายคำพูดคือ −
Ps "Punctuation, Open" Pe "Punctuation, Close" Pi "Punctuation, Initial quote (might behave like Ps or Pe depending on its usage)" Pf "Punctuation, Final quote (might behave like Ps or Pe depending on its usage)" Po "Punctuation, Other"
หากผู้ใช้ไม่แน่ใจเกี่ยวกับอินพุตที่เข้ารหัส UTF-8 สามารถวางโค้ดด้านล่างก่อนดำเนินการอื่น ๆ -
if ( !preg_match('/^\\X*$/u', $str)) {
$str = utf8_encode($str);
} หากข้อมูลจำเป็นต้องทำให้เป็นมาตรฐานในช่วง 0x80-0x9F สามารถใช้โค้ดด้านล่างได้ -
