Sang Pangeran Ketjil β€” in old Indonesian language style, written in old Van Ophuijsen orthography used in Indonesia before the independence.

Van Ophuijsen orthography is a system of romanisation or transcription for writing Old Indonesian language using the latin alphabet. It was developed by the Dutch linguist and scholar, J.W. van Ophuijsen, in the early 20th century. This orthography was primarily used to represent the sounds of Old Javanese, which is an ancient language spoken in Java island. The system is based on the principle of representing each sound in the language with a single letter or combination of letters in the latin alphabet, and it includes diacritical marks to indicate specific vowel sounds.
