Yes, but an intelligent man could understand that I have already found and applied this, but it is not enough

Hello, i use ajax, HtmlEditorExtender to let users writing their own description i store in database, and in my database i can see properly data store in table like this :

'🔸🖤 DANCE SQUARE 🖤🔸\n📝 LA TRILOGIE :\n3 dates à ne surtout pas manquer\n.\n🟧◾️ 29 Octobre - LA'

but when i read data by sql, in string variable, i lose all the specials characters like hearts in my example, all specials characters are replace by ? what should i do to keep specials characters ? (correctly store in database.) i read like this :

if (!res.IsDBNull(i))
ss {
return res.GetString(i);
}
else
{
return string.Empty;
}
