Joining Type - Transparent
Transparent is a classification for characters that have no effect on cursive joining behavior within a text, meaning they do not create a visual connection between adjacent letters and are effectively ignored for the purpose of determining whether a preceding and following character should join together. These characters, which include spaces, punctuation, diacritical marks, and certain control codes, are treated as invisible barriers that allow the letters on either side to maintain their isolated or independent forms, while not forcing a break in the logical sequence of shaping. This ensures that the joining decision is based solely on the nearest significant letter on each side, preserving the correct rendering of scripts that rely on connection, even when non-letter symbols or modifiers intervene.
