    Fix buffer overrun in EUC-KR conversion module (bz #24973)

    The byte 0xfe as input to the EUC-KR conversion denotes a user-defined
    area and is not allowed.  The from_euc_kr function used to skip two byt=
es
    when told to skip over the unknown designation, potentially running over
    the buffer end.
