Hi @"Hilary Farrell-Oracle" ,
Could you please help to log bugs related to emoji?
Recently, I found emoji might cause some weird bugs if I used them in my applications.
- emoji can not be saved in page designer after import
Steps:
- Use emoji in the content of a static content region
- then export
- and then import the appllication to apex.oracle.com
- then this emoji can not be changed any more in page designer
Error: when save, ORA-01426 prompt. This bug just exists on apex.oracle.com. Local ENV is ok to edit and update.

Workaround:
don't do this change in apex.oralce.com but in local Env. And then import again to the cloud.
- emoji cause import failed
Steps:
- use emoji in THEME42, especially in navigation bar list (list name)
- then export
- and them import to local Env or apex.oracle.com (APEX 5.1.0 or 5.1.1)
- import process failed
Error: PLS-00201: identifier 'WWV_OW_T_VARCHAR2' must be declared ORA-06550
Workaround:
From the error information, I guess the import procedure doesn't handle emoji, and emoji separates the normal string to cause WWV_FLOW_T_VARCHAR2 to be WWV_OW_T_VARCHAR2.
So remove emoji, import succeeds.
Thanks. Hope emoji bugs can be fixed soon.
B.R.
