47 * The index in g_chartab[] depends on 'encoding': |
| 7 | 48 * - For non-multi-byte index with the byte (same as the character). |
| 49 * - For DBCS index with the first byte. | |
| 50 * - For UTF-8 index with the character (when first byte is up to 0x80 it is | |
| 51 * the same as the character, if the first byte is 0x80 and above it depends | |
| 52 * on further bytes). | |

54 * The contents of g_chartab[]: |
| 7 | 55 * - The lower two bits, masked by CT_CELL_MASK, give the number of display |
| 56 * cells the character occupies (1 or 2). Not valid for UTF-8 above 0x80. | |
| 57 * - CT_PRINT_CHAR bit is set when the character is printable (no need to | |
| 58 * translate the character before displaying it). Note that only DBCS | |
| 59 * characters can have 2 display cells and still be printable. | |
| 60 * - CT_FNAME_CHAR bit is set when the character can be in a file name. | |
| 61 * - CT_ID_CHAR bit is set when the character can be in an identifier. | |
| 62 * | |
| 63 * Return FAIL if 'iskeyword', 'isident', 'isfname' or 'isprint' option has an | |
| 64 * error, OK otherwise. | |

| 2006 * removed. Assume a file name doesn't start with a space. | |
| 2007 * For multi-byte names, never remove a backslash before a non-ascii | |

| 2009 * characters. | |
