I was looking at some Thai crosswords, and I wondered what scripts
people do crosswords in. In Thai crosswords, the items in the squares
are preposed vowels, postposed vowels, and consonants along with
associated marks above and below (vowels above, vowels below, tone
marks, consonant killer). You can find a good example on line at
http://www.naewna.com/news.asp?ID=91533 (the answer is at the bottom,
upside down), though the grids are often notched for the marks above
and below as at

=50>

.)

What go in the letter squares in other scripts? I would guess that
the items in the squares were aksharas in most Indic scripts, but I
might be wrong. For example, do Tamil crosswords, if they exist, work
like Thai crosswords?
