Re: [New user] local horizontal and vertical corrections

This is in response to some oldish email of Sun, 19 Jan 2003.
I've been away and only just got around to reading my email.
The email message is included below.  My responses are

a) I recently added an option to the @Font symbol to give
   alignment through the baseline, but this is deliberately
   turned off in equations since they are the leading example
   of an application where it's good to get alignment through
   half the x-height.

b) I guess you could write u sub { i sup {1f @High} } to
   make the subscript symbol think it is being given a
   superscript of the same height as i sup 2.  You'd have
   to play with the 1f though.

c) Try tsub instead of sub, and if that isn't right, find
   the definition of tsub in LOUTLIB/include/eqf and write
   yourself a ttsub along the same lines.

d) I gather another user answered this.

    I am a new user. I came from TeX to groff !!! But I want to
    write a document with much mathematics, and I don't like
    groff for mathematical typesetting. I don't want either to user
    La(TeX) because I really don't like the Computer Modern Fonts.
    The font I use for everything is Utopia Type 1. I installed it
    for lout, everything is OK. I also Installed Coronet for
    calligrahic letters in equations.
      a) Speaking of Coronet:
         I have something like
         @Eq {u sub i = {Coronet Base 18pt} @Font l sub i}
         I put 18pt for optical reasons. Of course, base size is
         12pt for everything else like the first 'u'.
         But I would like to have the baseline of 'u' and baseline
         of 'l' (Coronet 18pt) to be the same !!! which isn't the case
         (probably because lout thinks the 'l' is an object that has
         for the baseline the middle of its height or some reason like
         that. The single correction I found is 9.4p @VShift. But in order
         to find 9.4p I had to look at the postscript output and try values
         until both baseline were the same. Is there a way to tell
         "keep the current baseline for the 'l'" ???
       b) If I put @Eq {u sub i = v sub {i sup 2}}
         I notice that both 'i' don't have the same baseline. I understand
         clearly why: {i sup 2} having a greater height than i. But I would
         like to have same baseline for both i and i². Is there a way to
         fix that ?
       c) With my calligraphic l sub i
          I notice there is a big amount of horizontal space between the
          'l' and the 'i' because of the shape of the 'l'. With troff
          I would put a backward horizontal movement: \h'-1p'. Is there
          a way to do that ? With LaTeX I would do the same thing by
          encapsulating the 'l' in a box with a null or very small width
          in order to let the processor think that 'l' has a smaller
          width than it really has. How can I do it with lout ?
        d) When I type normal text (not equations), I want to have
           fixed-width spaces before ?;:! (which is the rule in french).
           Is there something shorter than:
               hello world{4p @Wide {}}!
      Thank you for everything ;-)
