    We need to adapt to the new system of creation of domain names with graphical characters of Portuguese language like accented vowels and cedilha exclusively.

    We think to make a test in the (, initially.

    Would you give us an idea how to do this?

    We tried to create by WHM without success.




    I tried to translate below the text sent us from Fapesp (, if it could help you to understand better this matter:

    Since 2005/05/09, the brazilian register service ( started to accept register of domain names with the characters allowed in the Portuguese language (accented vowels and cedilha exclusively). This service uses technology IDNA[1 ] for international domínios in applications.

    This technology estimates the existence of support in the diverse applications (Browsers for HTTP, Customers of email for smtp etc...). It functions converting the addresses contends characters special for American National Standard Code for Information Interchange in a compatible codification with system DNS (ACE[1 ])..

    For register ends, an equivalence (SKI) in the comparison of domain names is established as already he was done in the case of the hyphen. The mapping will be carried through becoming the accented characters and cedilha, respectively, for its versions not accented and the "c". The register of a new domain will only be allowed when it will not have equivalence to a preexisting domain, or when the solicitant will be the same entity detainer of the domain equivalent. Thus the error is prevented to induce the users and a race to the register of names is not created.

    In the interface of consultations WHOIS, these domínios will appear with version IDNA and, then after that, in version ACE. Servers DNS will have to be configured with the name of domain in ACE.

    As example:
    IDNA pãoemaçã
    ACE xn -- poem-9qaeä

    Em uma consulta ao whois:
    > whois pãoemaçã
    domain: pãoemaçã

    This implementation is considered more the possible insurance, a time that if only limits to the characters of the Portuguese language. An eventual permission of use of characters in other alphabets would generate the preoccupying possibility of homográficos attacks.
