Maze generator using unicode line drawing characters

Maze generator

using unicode line drawing characters

This script will generate mazes in plain unicode text, which can then be pasted on irc for example:

Why? Beats me, but it's still fun.

Potential problems (most can be fixed by trying a few other monospaced fonts)

If the maze is garbage characters, your browser might render the utf-8 as another charset.
If the maze is just a matrix of squares, your font doesn't have unicode line drawing chars.
If the maze looks ok, but is full of little boxes, the font is missing the characters that draw a line from one direction and stops at the center.
If the right edge isn't straight, your monospaced font isn't monospaced.
If a maze looks like garbage if you paste it to people on IRC, whoever is looking at it is not using utf-8 and therefore should no longer be your friends
If the maze is made of ascii characters like pipes, asterisks, L and T, your browser is doing something funny (links/lynx/msie5 especially). Switch.
