Can't support UTF-8 caracters in name

Hi
I've lost a very long time to find why my app can't load Jakarta.
Finally, I've found `smtp.fromName` attribute can't support UTF-8 caracters, in my case the "é" letter
Using Jakarta 2.1.0, JDK17, Unix env

Start by reproducing the issue with Jakarta Mail 2.1.0 on JDK 17 and a Unix environment, setting smtp.fromName to a value containing the UTF-8 character "é". Trace how that value is handled when loading mail configuration; done means UTF-8 names load correctly without breaking ASCII names.
