97 * may be to have a second embedding control responsible for drawing borders
98 * and backgrounds eventually)

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