hi, the new draft draft-pechanec-pkcs11uri-18.txt addresses comments on the use of UTF-8 in labels and names. The issue is that the PKCS#11 specification does not comment on normalization of the UTF-8 encoded Unicode characters, it just says "UTF-8". So, it is RECOMMENDed now in draft 18 to use US-ASCII only but enough information is provided as to what SHOULD be done if characters outside of US-ASCII need to be used. link to a diff from the previous draft version 17 is as follows: https://tools.ietf.org/rfcdiff?url2=draft-pechanec-pkcs11uri-18.txt best regards, Jan. -- Jan Pechanec <jan.pechanec@xxxxxxxxxx>
