| 100 | * |

| 102 | * that we are part-way through a recognised ISO-2022 escape |
| 103 | * sequence. Five of those bits (31:27) give the index of |
| 104 | * the first member of the escapes list matching what we |
| 105 | * have so far; the remaining three (26:24) give the number |
| 106 | * of characters we have seen so far. |
| 107 | * |
| 108 | * - The top bit of s1 (bit 31) is non-zero at all times, to |
| 109 | * indicate that we have performed any necessary |
| 110 | * initialisation. When we start, we detect a zero s1 and |
| 111 | * respond to it by initialising the default container |
| 112 | * contents. |
| 113 | * |
| 114 | * - The next three bits of s1 (bits 30:28) indicate which |
| 115 | * _container_ is currently selected. This isn't quite as |
| 116 | * simple as it sounds, since we have to preserve memory of |
| 117 | * which of the SI/SO containers we came from when we're |
| 118 | * temporarily in SS2/SS3. Hence, what happens is: |
| 119 | * + bit 28 indicates SI/SO. |
| 120 | * + if we're in an SS2/SS3 container, that's indicated by |
| 121 | * the two bits above that being nonzero and holding |
| 122 | * either 2 or 3. |
| 123 | * + Hence: 0 is SI, 1 is SO, 4 is SS2-from-SI, 5 is |
| 124 | * SS2-from-SO, 6 is SS3-from-SI, 7 is SS3-from-SO. |
| 125 | * + For added fun: in an _8-bit_ ISO 2022 subset, we have |
| 126 | * the further special value 2, which means that we're |
| 127 | * theoretically in SI but the current character being |
| 128 | * accumulated is composed of 8-bit characters and will |
| 129 | * therefore be interpreted as if in SO. |
| 130 | * |
| 131 | * - The next nibble of s1 (27:24) indicates how many bytes |
| 132 | * have been accumulated in the current character. |
| 133 | * |
| 134 | * - The remaining three bytes of s1 are divided into four |
| 135 | * six-bit sections, and each section gives the current |
| 136 | * sub-charset selected in one of the possible containers. |
| 137 | * (Those containers are SI, SO, SS2 and SS3, respectively |
| 138 | * and in order from the bottom of s0 to the top.) |
| 139 | * |

| 141 | * data so far. |
