Question:
What are the restrictions for inserting data in "User tag 1" and "User tag 2" fields, like maximum number of characters, special characters and spaces?
Environment:
UIM 8.5.1
Controller 7.80 or later
Answer:
The user tags info is recorded in UIM DB, in CM_NIMBUS_ROBOT table, inside the "user_tag_1" and "user_tag_2" columns.

These fields are defined as VARCHAR(256). So, they can accept alphanumeric characters, with a limit of 256 characters.
