LHFONTS version 3.4 file T1inT2.en
==============================================================================
This file includes information about common parts and differences of T1 and T2
encodings and LH fonts and EC fonts(1.0). There is also explanation why it was
happen.
I.
File letextit.mf (for Italic font) has one serious difference for Typewriter
Italic fonts which was borrowed from CM textit.mf file: _first_ run _Italic_
letters and specials (dotless letters and f-ligs) then if monospace=true:
letter_fit:=0 and _then_ run uppercase letters and common roman/italic
specials.
EC Typewriter Italic extextit.mf run both Uppercase and Italic letters with
common letter_fit; in this case Uppercase letters look _much more_ narrower
than in slanted fonts and they should be unreadable in lower resolutions.
II.
Here goes information about signs placed in common part of T1 and T2 encodings
and differences of shapes, glyphs and codes (if they exist)
l -- heavily borrowed from CM or/and EC
c -- created for T2 encoding
* -- borrowed from EC but corrected for mentioned reasons
lgcspl.mf --
Metafont program for the characters in positions of ligatures
for the "caps and small caps" fonts
X2 T2*
l I "19
l J "1a
if roman_ec:
l FI,FL,FFI,FFL fi "1b-"1f -- for T2* stuff only
