Convert SIXEL to UBRL

The SIXEL, or "six pixels", is a bitmap graphics format created by Digital Equipment Corporation (DEC) for their terminals and printers. Initially designed for DEC dot matrix printers like the LA50, it enabled the efficient transfer of bitmap graphics using a series of ASCII characters. Each character represents a 6-pixel high row, making it suitable for 7-bit serial communication. This format was later adapted for modern terminal emulators, extending its utility beyond its original scope.

The UBRL file extension stands for Unicode Braille and is used to represent Braille characters using Unicode encoding. Developed to facilitate the exchange and storage of Braille content digitally, it ensures accessibility for individuals with visual impairments. UBRL files are associated with ImageMagick and support both uncontracted and contracted Braille fonts. This format allows for easy integration of Braille text into various applications and systems.
