BMPString in certificate extension field by webcrypto API?

Hi.
I have question.

does webcrypto API suport BMPString that is in certificate extension field
by the IETF PKIX RFC 3280 CertificatePolicies?

normally Korean(or non-ascii text) DisplayText are encoded to BMPString to
certificate.
because the MS explorer does not support UTF8String in DisplayText field.

for referencing, I paste part of RFC 3280 spec.

Qualifier ::= CHOICE {

cPSuri CPSuri,
userNotice UserNotice }


CPSuri ::= IA5String

UserNotice ::= SEQUENCE {

noticeRef NoticeReference OPTIONAL,
explicitText DisplayText OPTIONAL}


NoticeReference ::= SEQUENCE {

organization DisplayText,
noticeNumbers SEQUENCE OF INTEGER }


DisplayText ::= CHOICE {

ia5String IA5String (SIZE (1..200)),
visibleString VisibleString (SIZE (1..200)),
bmpString BMPString (SIZE (1..200)),
utf8String UTF8String (SIZE (1..200)) }
