Package: ghostscript
Version: 8.71~dfsg-4
Severity: important
Tags: sid
A program of mine that renders text by converting it to Unicode
encoding recently stopped working. The following PostScript sequence
illustrates the problem:
----
/tmpstr 255 string def
/Unicode /Decoding findresource
dup length dict /UnicodeEncode exch def
{exch UnicodeEncode 3 1 roll put} forall
32 1 126
{
dup tmpstr cvs print ( => ) print
dup UnicodeEncode exch known
{
UnicodeEncode exch get tmpstr cvs
}
{
(?)
}
ifelse
print
(\n) print
}
for
----
This gets the Unicode decoding resource and prints out the mapping from
printable ASCII characters to corresponding glyph names. Part of its
output is shown below:
104 => h
105 => i
106 => LJ010000
107 => LK010000
108 => LL010000
109 => LM010000
110 => n
111 => o
What are those "LJxxx", "LKxxx" etc glyph names? Similar odd names appear
at other places in the output. They fail to map to valid glyphs in the font,
and I end up with gaps in the text layout.
Ghostscript also displays the message "Warning: the map file cidfmap was not
found"
each time it starts. Could this be related?

Sorry, I figured out what the problem was: the Decoding dictionary
has multiple entries for the same character code. The bug is in my
code; that it didn’t show up before was probably because the entries
happened to be returned in just the right order.
Please close this bug as invalid.
Done with this email (by appending -done to the user part of the BTS
email address).
Thank you.
Well, thank you for being suspicious and reporting in the first place!
And apologies for being silent: I have a terrible habit of only
commenting when I have some new input - and unfortunately I am not that
much of an expert in Postscript (and others in the ghostscript team
apparently is quite busy with other things).
Please do not hesitate to file other bugreports. They are highly
appreciated, even if not responded to, and even if they turn out not to
be bugs after all.
Kind regards,
- Jonas
