Lines Matching defs:surrogate
32 * Encode the Unicode UTF-16 code unit c16, which may be surrogate
36 * If c16 is a high surrogate, no output will be produced, but c16
38 * passing the trailing low surrogate.
40 * If c16 is a low surrogate, it must have been preceded by a call
41 * with the leading high surrogate; at this point the combined
85 char16_t surrogate;
147 * 2. Pending high surrogate.
148 * 3. No pending high surrogate and c16 is a high surrogate.
149 * 4. No pending high surrogate and c16 is a low surrogate.
150 * 5. No pending high surrogate and c16 is a BMP scalar value.
160 * surrogate -- there's nothing we can legitimately do
