Convert RLA to UBRL6

The RLA file extension stands for Run-Length Encoded, Version A, a bitmap image format developed by Alias/Wavefront. It is primarily used for storing raster graphics with run-length encoding to compress image data efficiently. RLA files are compatible with various image viewing and editing software, such as XnView. This format was popularized in the early days of computer graphics for its ability to handle arbitrary image channels and support efficient storage of large images.

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.
