 ===========================
 
 Warn about confusable identifiers, i.e. identifiers that are visually close to
 each other, but use different Unicode characters. This detects a potential
 attack described in `CVE-2021-42574 <https://www.cve.org/CVERecord?id=CVE-2021-42574>`_.
 
 Example:
 
 .. code-block:: text
 
     int fo; // Initial character is U+0066 (LATIN SMALL LETTER F).
-    int 𝐟o; // Initial character is U+1234 (SUPER COOL AWESOME UPPERCASE NOT LATIN F) not U+0066 (LATIN SMALL LETTER F).
+    int 𝐟o; // Initial character is U+1D41F (MATHEMATICAL BOLD SMALL F) not U+0066 (LATIN SMALL LETTER F).
