When checking availability of the bi-directional idn domains in PBA (e.g.
الجزائر50.الجزائر), an error occurs:
Convert to IDN failed; uidna_IDNToASCII error: 66562 U_STRINGPREP_CHECK_BIDI_ERROR
Invalid domain name. Please enter valid domain name
According to RFC 5893 "Right-to-Left Scripts for Internationalized Domain Names for Applications (IDNA)" section 4.3 "Strings with Numbers" it is not a correct domain name. However as stated in RFC, one of the combination (
hebrew letters+digit or
digit+hebrew letters) shall be allowed.
Currently in PBA neither of them is possible, the feature request with id #PBA-39637 exists to implement the support of such domains.
