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
