Missing letters from the Hungarian character set

[RobEin]

Hi,

The following letters are missing from the Hungarian character set:
ő U+0151 (Latin Small Letter O with Double Acute)
Ő U+0150 (Latin Capital Letter O with Double Acute)

ű U+0171 (Latin Small Letter U with Double Acute)
Ű U+0170 (Latin Capital Letter U with Double Acute)

and maybe:
€ U+20ac (Euro Sign)

Thanks:
Robert
