Illegal Form-of-Use - Teradata VantageCloud Lake

See Ill-formed Code Unit Sequences for information about how ill-formed code unit sequences are handled in sessions with Unicode Pass Through (UPT) enabled.

In sessions where UPT is not enabled, the illegal form-of-use exception generates an illegal form-of-use error. External single-byte character sets do not have an illegal form-of-use but translations from ASCII with bytes above 7F can produce translation errors.

Example

Consider the s1string for the examples under this topic, where:

s1=92年03月10 日

If the string was modified as in the following example, an illegal form-of-use error is returned because the modified string is malformed.

Example: UTF8
