Convert HPGL to TXT BRAILLE6DOTS

The HPGL file extension, short for Hewlett-Packard Graphics Language, is a file format and printer control language developed by Hewlett-Packard in 1977 for use with their plotter printers, starting with the HP-9872. HPGL files contain commands that instruct plotters to draw images using lines rather than dots, making them essential in CAD applications and technical drawings. The language uses a series of two-letter codes followed by parameters to control the plotter's actions, such as moving the pen or drawing shapes.

A TXT file extension, associated with "Unicode Braille 6 Dots", refers to the representation of braille characters within the Unicode standard, specifically using a 6-dot cell configuration. This allows for the encoding of braille patterns, making it accessible for visually impaired users to read and write text digitally. The history of braille dates back to its invention by Louis Braille in the 19th century, and its inclusion in Unicode ensures compatibility across various digital platforms.
