Re: Undeclared glyphs


I have followed the discussion about 8r encoding, it was rather interesting.
But the latest Melissa's posting iritated me. Here is why.

As far as I undestand the purpose of DC fonts (and T1 encoding), they were
designed to help people, who are using character sets other than
plain ASCII. If you take a look at document 'dok.tex', which can be found
somewhere near Metafont sources of DC fonts, you can see, which nations
benefit by using T1 encoding and DC fonts.

It is quite sad that T1 encoding and ISO-Latin2 are so different, but
there are ways to go over that. I don't know, which encoding was
made earlier.

It is true, that most 'aditional' characters in DC fonts can be constructed
by using regular TeX commands, but the results of later are not very
satisfactory every time. Just an example: letter c vith check can be
constructed with TeX command '\v{c}', in T1 encoding one can get it with
'\char{"A3}' ... you can see the difference (the check on the character
constructed with '\v{c}' put too much to the left).

So, don't spit on T1 encoding if you don't really need the benefits it
has comparing to other encodings.

PS. Please, excuse me for using stronger words, I am just quite upset.
