It is Thai character (so suea, ส) with vowel (mai taikhu, -็) stacked together several times. In Mac OS X stacked vowels/tone markers will never appear beyond baseline[1][2] which is "correct" since we don't stack them vertically beyond 2 levels (vowel+tone marker, or 3 if you count the lower part); on Windows and maybe Linux it will appear stacked[2].
