 With regards to directionality, Siddhaṃ texts were usually read from left-to-right then top-to-bottom, as with Indic languages, but occasionally they were written in the traditional Chinese style, from top-to-bottom then right-to-left.Bilingual Siddhaṃ-Japanese texts show the manuscript turned 90 degrees clockwise and the Japanese is written from top-to-bottom, as is typical of Japanese, and then the manuscript is turned back again, and the Siddhaṃ writing is continued from left-to-right (the resulting Japanese characters look sideways).Over time, additional markings were developed, including punctuation marks, head marks, repetition marks, end marks, special ligatures to combine conjuncts and rarely to combine syllables, and several ornaments of the scribe's choice, which are not currently encoded.
