54 * The contents of g_chartab[]: |

| 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. | |

| 63 * Return FAIL if 'iskeyword', 'isident', 'isfname' or 'isprint' option has an | |
| 64 * error, OK otherwise. | |

| 7 | 2338 * backslash is not a normal file name character. |

| 2340 * it. This means it is not possible to use an environment variable after a | |
| 2341 * backslash. "C:\$VIM\doc" is taken literally, only "$VIM\doc" works. | |
| 2342 * Although "\ name" is valid, the backslash in "Program\ files" must be | |
| 2343 * removed. Assume a file name doesn't start with a space. | |
| 2344 * For multi-byte names, never remove a backslash before a non-ascii | |
| 2345 * character, assume that all multi-byte characters are valid file name | |
| 2346 * characters. | |
