Each profiles contains tables which describe * how a code point should be treated. The tables are broadly classified into *

*
• Unassigned Table: Contains code points that are unassigned * in the Unicode Version supported by StringPrep. Currently * RFC 3454 supports Unicode 3.2.
*
• Prohibited Table: Contains code points that are prohibited from * the output of the StringPrep processing function.
*
• Mapping Table: Contains code points that are deleted from the output or case mapped.
*

* * The procedure for preparing Unicode strings: *

*
1. Map: For each character in the input, check if it has a mapping * and, if so, replace it with its mapping.
*
2. Normalize: Possibly normalize the result of step 1 using Unicode * normalization.
*
3. Prohibit: Check for any characters that are not allowed in the * output. If any are found, return an error.
*
4. Check bidi: Possibly check for right-to-left characters, and if * any are found, make sure that the whole string satisfies the * requirements for bidirectional strings. If the string does not * satisfy the requirements for bidirectional strings, return an * error.
