 632     NB: faking a charcode here is problematic. The kEventTextInputUpdateActiveInputArea event is sent
 633     multiple times to update the active range during inline input, so this handler will often receive
 634     uncommited text, which should usually not trigger side effects. It might be a good idea to check the
 635     kEventParamTextInputSendFixLen parameter and verify if input is being confirmed (see CarbonEvents.h).
 636     On the other hand, it can be useful for some applications to react to uncommitted text (for example,
 637     to update a status display), as long as it does not disrupt the inline input session. Ideally, wx
 638     should add new event types to support advanced text input. For now, I would keep things as they are.
 639
 640     However, the code that was being used caused additional problems:
 641                     UInt32 message = (0  << 8) + ((char)uniChars[pos] );
 642     Since it simply truncated the unichar to the last byte, it ended up causing weird bugs with inline
 643     input, such as switching to another field when one attempted to insert the character U+4E09 (the kanji
 644     for "three"), because it was truncated to 09 (kTabCharCode), which was later "converted" to WXK_TAB
 645     (still 09) in wxMacTranslateKey; or triggering the default button when one attempted to insert U+840D
 646     (the kanji for "name"), which got truncated to 0D and interpreted as a carriage return keypress.
 647     Note that even single-byte characters could have been misinterpreted, since MacRoman charcodes only
 648     overlap with Unicode within the (7-bit) ASCII range.
 649     But simply passing a NUL charcode would disable text updated events, because wxTextCtrl::OnChar checks
 650     for codes within a specific range. Therefore I went for the solution seen above, which keeps ASCII
 651     characters as they are and replaces the rest with '?', ensuring that update events are triggered.
 652     It would be better to change wxTextCtrl::OnChar to look at the actual unicode character instead, but
 653     I don't have time to look into that right now.
