Dear all style-list,

in Thai text, we need the underline to skip all Thai below-level 
characters and also below-level part & tail of Thai characters

Some Thai character will be unseen, if the underline strike over it.
(e.g. U+0E3A  Thai Character Phinthu)

Considering Latin text, like English,
this is a case of gjpqy and some other characters,
like c with lower hook (cedilla).


Currently, CSS style doesn't allow us to do so.
will w3c has any plan to add new attribute to underline
to allow web developers choose their prefer style for underline ?

possible options
1) not skip
2) skip only whitespace
3) skip only below-base-line part-of-character
4) skip whitespace and below-base-line part-of-character


the basic idea of this arises from
http://bugzilla.mozilla.org/show_bug.cgi?id=156881


regards,
Art

FYI,
Thai character has 4 levels of displaying.
from highest to lowest level:
  top
  above (same level as accent mark of western)
  base  (same level as general western character)
  below
