+# Make sure all escape sequences are enclosed in \[..\] to prevent line wrapping issues
+
+### Problematic code:
+
+    PS1='\e[36m\$ \e(B\e[m'
+
+### Correct code:
+
+    PS1='\[\e[36m\]\$ \[\e(B\e[m\]'
+
+### Rationale:
+
+Bash is unable to determine exactly which parts of your prompt are text and which are terminal codes. You have to help it by wrapping invisible control codes in `\[..\]` (and ensuring that visible characters are not wrapped in `\[..\]`).
+
+Note: ShellCheck offers this as a helpful hint and not a robust check. Don't rely on ShellCheck to verify that your prompt is correct.
+
+### Contraindications
+
+None.
