cp850

Description of the page content

Forth program that creates PHP source code to define an array that will be used to translate characters from CP850 to Unicode.

Tags:

I programmed this tool in order to improve the WRS I wrote to manage programandala.net. I needed to translate the characters of my old DOS listings in order to include them into the web pages (I already had programmed the translations needed for the character sets of Sinclair QL, Sinclair ZX Spectrum, Psion 5mx and others). I got the the Unicode codes from the Wikipedia's page Code Page 850; I made a list with the hexadecimal codes and then the Forth program did the dirty work.

Source code

\ cp850.fs

\ This program creates PHP code with an array to translate CP850 codes into HTML Unicode.
\ Written in ANS Forth.
\ Tested with Gforth.

\ 2009-06-09: First version.
\ 2014-10-17: Changes:
\   - "<?php" and "?>" added to the output file;
\   - explicit hex notation used in the translation data;
\   - 'bye' added at the end of the process.
\   - source code layout changed;
\   - main word renamed to 'run'.

\ Usage:
\   gforth cp850.fs -e run > cp850.inc.php

\ CP850 translations to Unicode
