.\" definitions of nroff special characters
.\" The character definitions here operate on the "better ugly than invisible"
.\" principle, and try to approximate the character *somehow*.  They were
.\" tuned for a Teletype 40 line printer, but should give vaguely plausible
.\" results on any overprinting ASCII device.
.\"
.\" first, things that nroff considered builtins
.^c \ 1 \\
.^c e 1 \\
.^c ' 1 '
.^c ` 1 `
.^c - 1 -
.\" some things seem to assume that \+ is like \-
.^c + 1 +
.\" we do not do backslash-space here, it can't be done with .^c, but the
.\" other forms of space we can do
.^c 0 1 " 
.^c | 0
.^c ^ 0
.^c & 0
.\"
.\" and more normal characters
.\" note, the hyphenation logic knows about em
.^c em 2 --
.^c en 1 -
.\" hy is a special case, see above
