 609     NB: faking a charcode here is problematic. The kEventTextInputUpdateActiveInputArea event is sent
 610     multiple times to update the active range during inline input, so this handler will often receive
 611     uncommited text, which should usually not trigger side effects. It might be a good idea to check the
 612     kEventParamTextInputSendFixLen parameter and verify if input is being confirmed (see CarbonEvents.h).
 613     On the other hand, it can be useful for some applications to react to uncommitted text (for example,
 614     to update a status display), as long as it does not disrupt the inline input session. Ideally, wx
 615     should add new event types to support advanced text input. For now, I would keep things as they are.
 616
 617     However, the code that was being used caused additional problems:
 618                     UInt32 message = (0  << 8) + ((char)uniChars[pos] );
 619     Since it simply truncated the unichar to the last byte, it ended up causing weird bugs with inline
 620     input, such as switching to another field when one attempted to insert the character U+4E09 (the kanji
 621     for "three"), because it was truncated to 09 (kTabCharCode), which was later "converted" to WXK_TAB
 622     (still 09) in wxMacTranslateKey; or triggering the default button when one attempted to insert U+840D
 623     (the kanji for "name"), which got truncated to 0D and interpreted as a carriage return keypress.
 624     Note that even single-byte characters could have been misinterpreted, since MacRoman charcodes only
 625     overlap with Unicode within the (7-bit) ASCII range.
 626     But simply passing a NUL charcode would disable text updated events, because wxTextCtrl::OnChar checks
 627     for codes within a specific range. Therefore I went for the solution seen above, which keeps ASCII
 628     characters as they are and replaces the rest with '?', ensuring that update events are triggered.
 629     It would be better to change wxTextCtrl::OnChar to look at the actual unicode character instead, but
 630     I don't have time to look into that right now.
