pseudographics in Java

OK, so the title says it - i'd like to know something about this.

First, do I understand correctly that "Pseudographics" is just using special characters to draw the craphics (like =========== would be the top border of a window)? If not, then please elaborate?

Second, if the above was correct, then would I need to output the special characters by using some weird function which can output these special characters from the unicode table (sonething like getChar(34235)...)?

thanks!
