| michael@0 | 8 | File Name: 15.5.3.2-1.js |
| michael@0 | 9 | ECMA Section: 15.5.3.2 String.fromCharCode( char0, char1, ... ) |
| michael@0 | 10 | Description: Return a string value containing as many characters |
| michael@0 | 11 | as the number of arguments. Each argument specifies |
| michael@0 | 12 | one character of the resulting string, with the first |
| michael@0 | 13 | argument specifying the first character, and so on, |
| michael@0 | 14 | from left to right. An argument is converted to a |
| michael@0 | 15 | character by applying the operation ToUint16_t and |
| michael@0 | 16 | regarding the resulting 16bit integeras the Unicode |
| michael@0 | 17 | encoding of a character. If no arguments are supplied, |
| michael@0 | 18 | the result is the empty string. |
| michael@0 | 19 | |
| michael@0 | 20 | This test covers Basic Latin (range U+0020 - U+007F) |
