Symptoms

A domain transfer sales order fails with the following output:

Registrar declined request for domain transfer. Domain transfer could not be carried out successfully.
; You are using a charset that is not supported by the registry. (EF03078) Domain status:Prepared. Service Creation Failed: Domain transfer failed

/var/log/httpd/payment-sdk.log on the BA Application node contains the same error:

[Fri Oct 01 16:52:02 2021] [pid 3103] AH01215: <?xml version="1.0" encoding="UTF-8" standalone="no"?><response><result><data/><msg><text>You are using a charset that is not supported by the registry.</text><code>EF03078</code><type>error</type><object><type>OWNERC/organization</type><value>company\xc3\name\xe2\x80\x8b</value></object></msg><status><code>E0104</code><text>Domain transfer could not be carried out successfully.</text><type>error</type><object><type>domain</type><value>domain.com</value></object></status></result><stid>20211001-app2-218485</stid></response>

Cause

\xe2\x80\x8b from the account name corresponds to U+200B, which is a Zero Width Space. This character is prohibited by the registry and must not be used.

Resolution

Change the account name removing the invisible character and send a new transfer request to registrar by resubmitting the order.
