Encoding Vedic Characters

The Vedic Unicode Proposal recommends the addition of Vedic characters to the Unicode standard so that tone marks that appear in red in this palmleaf manuscript of the Vājasaneyisaṃhitā may be accurately represented in print.

LIES Appendix B

The Sanskrit Library Phonetic Basic encoding scheme (SLP1) attempts to meet high standards of unambiguous encoding while restricting encoding to 75 codepoints in the ASCII character set. SLP1 utilizes 57 codepoints to encode segments: 53 to represent phonetic segments and four to represent punctuation. In addition SLP1 utilizes 18 codepoints to encode phonetic features: three to indicate stricture, five to indicate length, eight to indicate tone, and one to indicate nasalization….


SLP1Basic Segments


B.3 Modifiers

Modifiers are added after a character to indicate variations in segment stricture, length, accent, and nasalization, in the order stated. Prolonged length, accent, and nasalization occur in classical Sanskrit as well as Vedic. Modifiers are used in combination to indicate special features of stricture, length, accent, and nasalization in Vedic.


B.3.1 Stricture

_ heaviness [used for semivowels y or v] = lightness [used for semivowels y or v]

! lack of release (abhinidhāna)[used for stops or semivowels y, v, or l]


B.3.2 Length* subsegmental epenthetic vowel (svarabhakti)

# length of half a mora

1 length of one mora [used in Vedic after shortagitated kampa; short e, o; and heavy anusvāra]

1# slightly lengthened

2 length of two morae [used for dvimātra anusvāra inVedic]

3 prolonged length of three morae [used for plutavowels]

4 prolonged length of four or more morae [used inraṅga]


B.3.3 Accent

/ high pitch

\ low pitch

^ circumflex

6 extra low tone

7 low tone

8 high tone

9 extra high tone

+ sharpness


B.3.4 Nasalization~ nasalization

Yamas

20 epenthetic nasalized segments:k~, kh~, . . . , b~, bh~

4 four epenthetic nasalized segments:k~, kh~, g~, gh~

20 replacements for a non-nasal stop before a nasal: k~, kh~, . . . , b~, bh~ (Ṛkprātiśākhya)
