Why no non-English Characters in IDs and Passwords?
When you sign in,
your password and ID are encoded for security reasons. This encoding method does
not allow for characters outside the normal English character set. The following
is a list of acceptible characters:
<space> ! " # $ % ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 :
; < = > ? @ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \
] ^ _ ` a b c d e f g h i j k l m n o p q r s t u v w x y z { | }
