I am not sure that would fix the issue, more likely compound the issue
making it even more blurry what the semantic purpose is. HTML5 make
both <i> and <e> semantic ... and by the definition the style of the
elements is not necessarily italic. <em> for instance would be script
dependant, <i> may be partially script dependant when another
appropriate semantic tag is missing. A character/encoding level
distinction is just going to compound the mess.
A good point, too. While italics are being used sort of as an example,
what the "evidence" really is for (and by evidence I mean what I alluded
to at the end of my last post, over centuries of writing) is that people
like to *emphasize* things from time to time. It's really more the
semantic side of "this text should be read louder." So not so much
"italic marker" but "emphasis marker."
But... that ignores some other points made here, about specific meanings
attached to italics (or underlining, in some settings), like
distinguishing book or movie titles (or vessel names) from common or
proper nouns. Is it better to lump those with emphasis as "italic", or
better to distinguish them semantically, as "emphasis marker" vs "title
marker"? And if we did the latter, would ordinary folks know or care to
make that distinction? I tend to doubt it.
My main point in suggesting that Unicode needs these characters is
that italic has been used to indicate specific meaning - this text
is somehow special - for over 400 years, and that content should
be preserved in plain text.
Underlying, bold text, interletter spacing, colour change, font style
change all are used to apply meaning in various ways. Not sure why
italic is special in this sense. Additionally without encoding the
meaning of italic, all you know is that it is italic, not what
convention of semantic meaning lies behind it.
Um... yeah. That's what I meant, also.
And I am curious on your thoughts, if we distinguish italic in
Unicode, encode some way of spacifying italic text, wouldn't it make
more sense to do away with italic fonts all together? and just roll
the italic glyphs into the regular font?
Eh. Fonts are not really relevant to this. Unicode already has more
characters than you can put into a single font. It's just as sensible,
still, to have italic fonts and switch to them, just like you have to
switch to your Thai font when you hit Thai text that your default font
doesn't support. (However, this knocks out the simplicity of using
OpenType to handle it, as has been suggested.)
