         This is defined as the zero based index of the character position to
         the right of the insertion point. For example, if the insertion point
-        is at the end of the single-line text control, it is equal to both
-        GetLastPosition() and @c "GetValue().Length()" (but notice that the latter

-        The following code snippet safely returns the character at the insertion
-        point or the zero character if the point is at the end of the control.
+        Notice that insertion position is, in general, different from the index
+        of the character the cursor position at in the string returned by
+        GetValue(). While this is always the case for the single line controls,
+        multi-line controls can use two characters @c "\\r\\n" as line
+        separator (this is notably the case under MSW) meaning that indices in
+        the control and its string value are offset by 1 for every line.
+
+        Hence to correctly get the character at the current cursor position,
+        taking into account that there can be none if the cursor is at the end
+        of the string, you could do the following:
 
         @code
-        char GetCurrentChar(wxTextCtrl *tc) {
-            if (tc->GetInsertionPoint() == tc->GetLastPosition())
