After using csalter.sql to migrate the database character set from single-byte to AL32UTF8/UTF8, queries sporadically fail with the following errors:

ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00210: expected '<' instead of '¯'
Error at line 1
ORA-06512: at "USER.PACKAGE", line 726
ORA-06512: at line 4

XDB can but doesn't have to be installed for this problem to occur.

An errorstack trace for the ORA-19202 error is generated by executing the statement below before running the failing query:

SQL> alter session set events '19202 trace name ERRORSTACK level 3';

The trace file shows the following function calls in the stack trace:
