प्रत्येक यूनिकोड वर्ण ठीक एक "सामान्य श्रेणी" से संबंधित है।
इनमें से, जिनमें उद्धरण वर्ण हो सकते हैं, वे हैं -
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"
यदि उपयोगकर्ता सुनिश्चित नहीं है कि इनपुट UTF-8 एन्कोडेड है, तो नीचे दिए गए कोड को अन्य ऑपरेशन करने से पहले रखा जा सकता है -
if ( !preg_match('/^\\X*$/u', $str)) {
$str = utf8_encode($str);
} यदि डेटा को 0x80-0x9F की सीमा में सामान्यीकृत करने की आवश्यकता है, तो नीचे दिए गए कोड का उपयोग किया जा सकता है -
