Convert PBM to UBRL6

The PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.

The UBRL6 file extension, short for Unicode Braille 6 Dots, is a text encoding format that uses a 6-dot braille cell to represent characters, symbols, and punctuation marks. It enables the conversion of text into a tactile code system, facilitating reading for individuals with visual impairments. UBRL6 supports both uncontracted and contracted braille fonts and leverages Unicode to cover a wide range of characters from different writing systems. This format is particularly useful for developers and organizations working on accessibility solutions.
