+    NB: faking a charcode here is problematic. The kEventTextInputUpdateActiveInputArea event is sent
+    multiple times to update the active range during inline input, so this handler will often receive
+    uncommited text, which should usually not trigger side effects. It might be a good idea to check the
+    kEventParamTextInputSendFixLen parameter and verify if input is being confirmed (see CarbonEvents.h).
+    On the other hand, it can be useful for some applications to react to uncommitted text (for example,
+    to update a status display), as long as it does not disrupt the inline input session. Ideally, wx
+    should add new event types to support advanced text input. For now, I would keep things as they are.
+
+    However, the code that was being used caused additional problems:

                     UInt32 message = (0  << 8) + ((char)uniChars[pos] );
                     UInt32 message = (0  << 8) + ((char)uniChars[pos] );

+    Since it simply truncated the unichar to the last byte, it ended up causing weird bugs with inline
+    input, such as switching to another field when one attempted to insert the character U+4E09 (the kanji
+    for "three"), because it was truncated to 09 (kTabCharCode), which was later "converted" to WXK_TAB
+    (still 09) in wxMacTranslateKey; or triggering the default button when one attempted to insert U+840D
+    (the kanji for "name"), which got truncated to 0D and interpreted as a carriage return keypress.
+    Note that even single-byte characters could have been misinterpreted, since MacRoman charcodes only
+    overlap with Unicode within the (7-bit) ASCII range.
+    But simply passing a NUL charcode would disable text updated events, because wxTextCtrl::OnChar checks
+    for codes within a specific range. Therefore I went for the solution seen above, which keeps ASCII
+    characters as they are and replaces the rest with '?', ensuring that update events are triggered.
+    It would be better to change wxTextCtrl::OnChar to look at the actual unicode character instead, but
+    I don't have time to look into that right now.
