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