The comment for AltGr+Shift+S (key <AC02>) on the two OLPC layouts ('olpc' and 'olpcm') in the 'us' file indicates that it is "uppercase S sharp", but the character they produce is 0x1001E9C. U+1E9C is "LATIN SMALL LETTER LONG S WITH DIAGONAL STROKE". I think this may have been intended to be U+1E9E, "LATIN CAPITAL LETTER SHARP S".
Thank you, good catch! Fixed!
