* Unsafe/translated characters in the filesystem.
60
* LDIF_UNSAFE_CHAR(c) returns true if the character c is not to be used
61
* in relative filenames, except it should accept '\\' even if unsafe and
62
* need not reject '{' and '}'. The value should be a constant expression.
64
* If '\\' is unsafe, #define LDIF_ESCAPE_CHAR as a safe character.
66
* If '{' and '}' are unsafe, #define IX_FSL/IX_FSR as safe characters.
67
* (Not digits, '-' or '+'. IX_FSL == IX_FSR is allowed.)
69
* Characters are escaped as LDIF_ESCAPE_CHAR followed by two hex digits,
70
* except '\\' is replaced with LDIF_ESCAPE_CHAR and {} with IX_FS[LR].
71
* Also some LDIF special chars are hex-escaped.
73
* Thus an LDIF filename is a valid normalized RDN (or suffix DN)
74
* followed by ".ldif", except with '\\' replaced with LDIF_ESCAPE_CHAR.
80
* Unix/MacOSX version. ':' vs '/' can cause confusion on MacOSX so we
81
* escape both. We escape them on Unix so both OS variants get the same
84
#define LDIF_ESCAPE_CHAR '\\'

110
* Test for unsafe chars, as well as chars handled specially by back-ldif:
111
* - If the escape char is not '\\', it must itself be escaped. Otherwise
112
* '\\' and the escape char would map to the same character.
113
* - Escape the '.' in ".ldif", so the directory for an RDN that actually
114
* ends with ".ldif" can not conflict with a file of the same name. And
115
* since some OSes/programs choke on multiple '.'s, escape all of them.
116
* - If '{' and '}' are translated to some other characters, those
117
* characters must in turn be escaped when they occur in an RDN.
