The following is a proposal half-width Katakana encoding for the DCPU-16, fitting into the system's limited 7-bit address space for characters. The characters replaced are mostly box-drawing characters and a few punctuation marks. The Latin alphabet remains intact.

    Characters above 0x3E and below 0x7F are the same as the default font glyphs
