5 minute guide to encoding bangla in unicode
(a howto by example)

NOTES:
a. This should work without modification for ahamio too
b. In all cases where unicode code values are shown, they are in the order
they should be stored
in memory (eg. in a string or in a file)
c. A good resource is the unciode indic faq at
http://www.unicode.org/unicode/faq/indic.html

1. Get hold of the unicode chart for bangla/ahamio
http://www.unicode.org/charts/PDF/U0980.pdf

2. Vowel modifiers (i-kar, e-kar...)

ka-yhoshoi = 0x0995 0x09bf
ka-dirghoi = 0x0995 0x09c0
ka-hoshou = 0x0995 0x09c1

[modifier always comes after the consonant or conjunct consonant]

3. Chondrobindu

ka-chandrabindu = 0x0995 0x0981

[comes after the consonant or conjunct, like a kar]

4. Consonant conjuncts (ka-y-ta, ka-y-murdhannesha)

ka-y-ta = 0x0995 0x09cd 0x099f
ka-y-murdhannesha = 0x0995 0x09cd 0x09b7

[join the components of the conjunct with 0x09cd = hashanta]

For conjuncts with kar just assume the conjunct is a single consonant...

ka-y-ta-y-hoshhoi = 0x0995 0x09cd 0x09a4 0x09bf

5. Raphola (ka-y-ra)

[this is just a conjunct with the last consonant as ra
eg. ka-y-raphola = 0x0995 0x09cd 0x09b0]

6. Jawphola (ka-y-ontestojaw)

[this is just a conjunct with the last consonant as ontestojaw
eg. ka-y-ontestojaw = 0x0995 0x09cd 0x09af]

7. Reph (ka-y-reph)

[this is just a conjunct with the first consonant as ra
eg. ka-y-reph = 0x0995 0x09cd 0x09af]

8. Hahsanta (ka-hashanta)

when you want an explicit hashanta use the "zero width non joiner" 0x200c
to demarcate this

ka-y-hashanta = 0x0995 0x09cd 0x200c (0x09cd is still the hashanta sign)

9. Khondo-ta (ta-hashanta)

Khondo-ta is basically ta-y-hashanta, so from point 8

ta-y-hashanta = 0x09a4 0x09cd 0x200c


10. Punctuation
dari is 0x0964
double dari is 0x0965
all other punctuation marks isomorphic (here, identical) with latin.
