Unicode Status for Yi
In The Unicode Standard, Yi script implementation is discussed in Chapter 18: East Asia
.
The Yi script was first encoded in The Unicode Standard version 3.0. The script is encoded in the following blocks:
| Blocks | Character Range | Added in Unicode Version | Documentation |
|---|---|---|---|
| Yi Syllables | A000..A48F | 3.0 | UA000.pdf |
| Yi Radicals | A490..A4CF | 3.0 | UA490.pdf |
Subsequent to version 3.0, the following characters have been added to the Yi script:
| Characters | Unicode Version | Documentation |
|---|---|---|
| A4A2..A4A3 | 3.2 | n2207.pdf |
| A4B4 | 3.2 | n2207.pdf |
| A4C1 | 3.2 | n2207.pdf |
| A4C5 | 3.2 | n2207.pdf |
