NAME

Tchars − Translate characters for Troff.

SYNOPSIS

@BINDIR@/tchars [−e] file

DESCRIPTION

Tchars is a troff pre-processor which translate some ascii code to complex utf-8 characters. Actually, it can only translate a subset of betacode to polytonic greek.

OPTIONS

• −e: Escape characters: print troff utf-8 escape sequence in the form of \U’xxxx’ instead of printing the utf-8 character itself.

MACROS

In the troff document, characters that has to be translated must be indicated by one of the following macros:

• CW code after before: Transalte code, and append before and after just before and after the translation.
• CL code [code...]: Translate the whole line following CL.
• CS: Begin a block that has to be translated. Must be followed by CE.
• CE: Close a block that has to be translated.

For tchars to work, you must define these macro to call a font which contain polytonic greek characters, as follow, for example:

.fp 0 G GFSPyrsos otf \" Pyrsos from Greek Font Society
.de CW
\\$3\fG\\$1\fR\\$2
..
.de CL
\fG\\$*\fR
..
.de CS
.    ft G
..
.de CE
.    ft R
..
