Try this one, I think will help you

pawn Код:

GiveNameSpace(str[])
{
    new strl;
    strl=strlen(str);
    while(strl--) {
    if(str[strl]=='_')  str[strl]=' ';
    }
    return 0;
}

For example:

pawn Код:

new myname[MAX_PLAYER_NAME];
GetPlayerName(playerid, myname, sizeof(myname));
GiveNameSpace(myname);
new string[128];
format(string, sizeof(string), "%s", myname(playerid));
