Status: Open Priority: 3 Submitted By: Martin Schröder (oneiros) Assigned to: The Thanh Han (hanthethanh) Summary: /Names array not sorted correctly Category: None Group: v1.40.6 Resolution: Accepted

Initial Comment: Axel Berger and Heiko Oberdiek report an error with the sorting of the /Names array: /Names [(cite.Kr07) 44 0 R (cite.Li08) 45 0 R (cite.M\37403) 23 0 R (cite.Mi00) 47 0 R (cite.Mi84) 48 0 R (cite.Mo04) 50 0 R] "cite.Mü03" (= "cite.M\37403") should come after "cite.Mo04". A test file with output is attached. ----------------------------------------------------------------------

Message: thanks Heiko for the patch, hence I reopened this bug report. ---------------------------------------------------------------------- Comment By: Heiko Oberdiek (oberdiek) Date: 2009-04-06 03:49 Message: Sorry, I cannot accept the rejection, because the problem cannot be fixed at macro level unless * some characters (backslash, parentheses, ...) must be forbidden, * octal escape sequences are used for *every* character of the destination name (otherwise a large amount of programming work is needed to prevent that the bug is triggered.) Therefore I have written patch #3886 that fixes the comparison function `str_less_str' that is used for the sorting of destination names. Yours sincerely Heiko ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2009-04-05 22:55 Message: since the beginning we chose not to parse pdf string of \pdf* commands. Fixing this now would mean a too big change in pdftex code. Sorry. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2008-05-27 16:48 Message: ok then this should be fixed as the spec says. BTW, it doesn't really solve the reported problem (ü will come after eg z). ---------------------------------------------------------------------- Comment By: Hans Hagen (hagen) Date: 2008-05-27 16:03 Message: the spec says: The Names entries in the leaf (or root) nodes contain the tree’s keys and their associated values, arranged in key-value pairs and sorted lexically in ascending order by key. Shorter keys appear before longer ones beginning with the same byte sequence. The encoding of the keys is immaterial as long as it is self-consistent; keys are compared for equality on a simple byte-by-byte basis. so, it's just bytes ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2008-05-27 15:43 Message: this is a problem, but it's not clear to me how it should be fixed. Assume that we translate "\374" to the corresponding charcode (0374 = 252) before sorting, then how we decide the lexicographic order of that char? it can be intepreted as ü but also can be eg ytilde or something different, depending on the encoding we use.
