74 * Unsafe/translated characters in the filesystem.
76 * LDIF_UNSAFE_CHAR(c) returns true if the character c is not to be used
77 * in relative filenames, except it should accept '\\', '{' and '}' even
78 * if unsafe. The value should be a constant expression.
80 * If '\\' is unsafe, #define LDIF_ESCAPE_CHAR as a safe character.
81 * If '{' and '}' are unsafe, #define IX_FSL/IX_FSR as safe characters.
82 * (Not digits, '-' or '+'. IX_FSL == IX_FSR is allowed.)
84 * Characters are escaped as LDIF_ESCAPE_CHAR followed by two hex digits,
85 * except '\\' is replaced with LDIF_ESCAPE_CHAR and {} with IX_FS[LR].
86 * Also some LDIF special chars are hex-escaped.
88 * Thus an LDIF filename is a valid normalized RDN (or suffix DN)
89 * followed by ".ldif", except with '\\' replaced with LDIF_ESCAPE_CHAR.
95 * Unix/MacOSX version. ':' vs '/' can cause confusion on MacOSX so we
96 * escape both. We escape them on Unix so both OS variants get the same

125 * Test for unsafe chars, as well as chars handled specially by back-ldif:
126 * - If the escape char is not '\\', it must itself be escaped. Otherwise
127 * '\\' and the escape char would map to the same character.
128 * - Escape the '.' in ".ldif", so the directory for an RDN that actually
129 * ends with ".ldif" can not conflict with a file of the same name. And
130 * since some OSes/programs choke on multiple '.'s, escape all of them.
131 * - If '{' and '}' are translated to some other characters, those
132 * characters must in turn be escaped when they occur in an RDN.
