Add diagonal crosses, such as 'x', 'X' and U+00D7 MULTIPLICATION SIGN;
they are used for Lao (both Lao script and Tai Tham script), and I have
seen the cross used for Khmer. U+1D5D1 MATHEMATICAL SANS-SERIF SMALL X
and U+1D5B7 MATHEMATICAL SANS-SERIF CAPITAL X are particularly suitable
for the role - serifs are dispreferred.
Remove ZWSP - it is not a space (it has general category 'other,
format') and has no width, making it unsuitable as a place holder.
Richard.
