⊭ is the Unicode character NOT TRUE, code point U+22AD (decimal 8877) in the Mathematical Operators block, added in Unicode 1.1. In HTML write ⊭, and in UTF-8 it is the 3 bytes E2 8A AD.
Codes
| Where | How to write it |
|---|---|
| Code point | U+22AD |
| Decimal | 8877 |
| UTF-8 bytes | E2 8A AD |
| UTF-16 (big-endian) | 22AD |
| UTF-32 | 000022AD |
| HTML decimal | ⊭ |
| HTML hex | ⊭ |
| HTML named | ⊭ |
| CSS | \22AD |
| JavaScript | \u22AD |
| JSON | \u22AD |
| Python | \u22AD |
| Python by name | \N{NOT TRUE} |
| Java, C# | \u22AD |
| Rust, Swift | \u{22AD} |
| Go, C, C++ | \u22AD |
| URL (percent-encoded) | %E2%8A%AD |
JavaScript and JSON strings store text as UTF-16, so this character is one code unit long. Python 3 strings count code points, so its length there is 1.

Decomposition
NOT TRUE is canonically equivalent to the sequence below. Normalising text to NFD splits it into these parts; NFC joins them back into U+22AD. Search and comparison should normalise first, or the two spellings will not match.
