To get the value for Person or Group Column Type after removing the special characters from it, use this function

private string  GetValue(SPListItem item, SPField gpField)
{
    string currentValue = item[gpField.Title].ToString();
    SPFieldLookup field = (SPFieldLookup)gpField;
    SPFieldLookupValue fieldValue = (SPFieldLookupValue)field.GetFieldValue(currentValue);
    return fieldValue.LookupValue;
}

to call it

string strName = GetValue(spListItem, spListItem.Fields["fieldName"]);
