I'm implemeting the specific standard caled as hip, in which I have ', '=', as a diacritics marks. So I know about \'s\'S, but since the are not in the hip standard I can't use them. So I have a two kinds of letter sequences: usual letters (like a-z, and capital letter (like A-Z). And also have a control chars like (', =, etc), which interpreted as a diacritic sign. so when I put in tex doc:


It is correctly converted (with my font of course) to

But when type the capital version of the char:


Tex overdraws the char (using the same accent char), thus the char is begin overdrawn with non-capttal accent, and positioned inside that char.

So my question is how to correctly fix the virtual font file (.vpl) to support either replace that accent diacritic mark to that one, which has a upcase position, and can be correctly drawn over the capital char, or how to move the char to a new vertical position?

If that is impossible just with virtual font, how can I do that with tex?

The .vpl file is here.

    Could you give a minimal code (I can't use s' by default) and maybe link to this .vpl you are using? Thanks. – LaRiFaRi Feb 20 '15 at 9:14

    The .vpl file doesn't seem to do what you want; just define a ligature for s' pointing to the slot for ś and no ligature for S'. If you don't have a slot for ś, then there's nothing you can do, because neither macros nor ligatures look back. – egreg Mar 22 '15 at 10:39

Here are two ways how I would do that. The second one gives you more flexibility if you want to switch the font for this symbol or alike...

I do not know about your s' approach.

  • can I just type: S' to have S with accent? – Малъ Скрылевъ Feb 20 '15 at 9:36
  • @MalSkrilew No, sorry. Please show an MWE in which this works. I have never seen that before to be true – LaRiFaRi Feb 20 '15 at 9:46
  • ok, s' just works, S' doesn't – Малъ Скрылевъ Feb 20 '15 at 12:29
