language written in some Indic scripts exaggerate angles or round shapes, but this serves only to mask the underlying similarities. Nagari script favours symmetry set with squared outlines and right angles. In contrast, Sanskrit written in the Bangla script emphasizes the acute angles while the neighbouring Odia script emphasizes rounded shapes and uses cosmetically appealing "umbrella-like curves" above the script symbols. In the south, where Dravidian languages predominate, scripts used for Sanskrit include the Kannada, Telugu, Malayalam and Grantha alphabets. Transliteration schemes, Romanisation Since the late 18th century, Sanskrit has been transliterated using the Latin alphabet. The system most commonly used today is the IAST (International Alphabet of Sanskrit Transliteration), which has been the academic standard since 1888. ASCII-based transliteration schemes have also evolved because of difficulties representing Sanskrit characters in computer systems. These include Harvard-Kyoto and ITRANS, a transliteration scheme that is used widely on the Internet, especially in Usenet and in email, for considerations of speed of entry as well as rendering issues. With the wide availability of Unicode-aware web browsers, IAST has become common online. It is also possible to type using an alphanumeric keyboard and transliterate to Devanagari using software like Mac OS X's international support. European scholars in the 19th century generally preferred Devanagari for the transcription and reproduction of whole texts and lengthy excerpts. However, references to individual words and names in texts composed in European Languages were usually represented with Roman transliteration. From the 20th century onwards, because of production costs, textual editions edited by Western scholars have mostly been in Romanised transliteration. Epigraphy The earliest known stone inscriptions in Sanskrit are in the Brahmi script from the first century BCE. These include the Ayodhyā (Uttar Pradesh) and Hāthībādā-Ghosuṇḍī (near Chittorgarh, Rajasthan) inscriptions. Both of these, states Salomon, are "essentially standard" and "correct Sanskrit", with a few exceptions reflecting an "informal Sanskrit usage". Other important Hindu inscriptions dated to the 1st century BCE, in relatively accurate classical Sanskrit and Brahmi script are the Yavanarajya inscription on a red sandstone slab and the long Naneghat inscription on the wall of a cave rest stop in the Western Ghats. Besides these few examples from the 1st century BCE, the earliest Sanskrit and hybrid dialect inscriptions are found in Mathura (Uttar Pradesh). These date to the 1st and 2nd century CE, states Salomon, from the time of the Indo-Scythian Northern Satraps and the subsequent Kushan Empire.
