Do you know if these VM changes are already part of recent VM? or if it
can become part?

Thanks

Hello Hilarie,
Recently, Hachisuka-San in Aichi Sangyo University has resolved the issue
of Scratch in Linux.
http://www.asu.ac.jp/hachi/v3/scratch14ime.html
Unfortunately, this page is written in Japanese. (However you can see 
codes.)
The resolution of the problem in DrGeo is as follows:
1. In drgeo.sh, add exec options '-compositioninput' like
exec "$VM/pharo" \
  -plugins "$VM" \
  -encoding utf-8 \
  -vm-display-X11 \
  -compositioninput \
  "$image"
2. Change recordPendingKeys(void) in vm-display-X11/sqUnixX11.c as 
follows and
rebuild vm-display-X11.
static int recordPendingKeys(void)
{
  if (inputCount <= 0) {
    if (inputBuf != inputString) {
      free(inputBuf);
      inputBuf= inputString;
    }
    return 0;
  }
int utf32 = 0;
  while (inputCount > 0) {
  //110x xxxx 10xx xxxx
  if(inputCount >= 2 &&
     pendingKey[0] >= 0xc0 && pendingKey[0] <= 0xdf && 
     pendingKey[1] >= 0x80 && pendingKey[1] <= 0xbf)
      {
      utf32 = ((pendingKey[0] & 0x1f) << 6) | 
      	 (pendingKey[1] & 0x3f);
          recordKeyboardEvent(0, EventKeyDown, modifierState, utf32);
          recordKeyboardEvent(0, EventKeyChar, modifierState, utf32);
      pendingKey+=2;
      inputCount-=2;
  //1110 xxxx 10xx xxxx 10xx xxxx
  } else if(inputCount >= 3 &&
        pendingKey[0] >= 0xe0 && pendingKey[0] <= 0xef && 
        pendingKey[1] >= 0x80 && pendingKey[1] <= 0xbf && 
        pendingKey[2] >= 0x80 && pendingKey[2] <= 0xbf)
      {
      utf32 = ((pendingKey[0]  & 0x0f) << 12) | 
      	((pendingKey[1] & 0x3f) << 6) | 
      	 (pendingKey[2] & 0x3f);
          recordKeyboardEvent(0, EventKeyDown, modifierState, utf32);
          recordKeyboardEvent(0, EventKeyChar, modifierState, utf32);
      pendingKey+=3;
      inputCount-=3;
  //1111 0xxx 10xx xxxx 10xx xxxx 10xx xxxx
  } else if(inputCount >= 4 &&
        pendingKey[0] >= 0xf0 && pendingKey[0] <= 0xf7 && 
        pendingKey[1] >= 0x80 && pendingKey[1] <= 0xbf && 
        pendingKey[2] >= 0x80 && pendingKey[2] <= 0xbf && 
        pendingKey[3] >= 0x80 && pendingKey[3] <= 0xbf)
      {
      utf32 =	((pendingKey[0] & 0x07) << 18) | 
      	((pendingKey[1] & 0x3f) << 12) |
      	((pendingKey[2] & 0x3f) << 6) |
      	 (pendingKey[3] & 0x3f);
          recordKeyboardEvent(0, EventKeyDown, modifierState, utf32);
          recordKeyboardEvent(0, EventKeyChar, modifierState, utf32);
      pendingKey+=4;
      inputCount-=4;
  } else {
          recordKeyboardEvent(*pendingKey, EventKeyDown, modifierState, 0);
          recordKeyboardEvent(*pendingKey, EventKeyChar, modifierState, 0);
          recordKeystroke(*pendingKey); /* DEPRECATED */
      pendingKey++;
      inputCount--;
  }
  }
  return 1;
}
3. Exchange vm-display-X11 in DrGeo.app/Contents/Linux.
I tried this resolution. Finally I can put japanese character in 
DrGeo in LinuxMint 16.
