SVG-Plot fails with ampersand in schematic or board filename

[Bernd Wiebus]

If i plot to SVG, i get an error message from Inkscape or Gimp, when the filename of the original schematic or board file contains an ampersand "&". In windows and linux, ampersands are legal at filenames, and kicad, Gimp and Inkscape aczept filenames with ampersand. But in this case, kicad creates a SVG file with a title block (<title> ~~~ </title>) which contains the original filename and so the ampersand. In this title block, a ampersand somehow is fatal (perhaps escape sequence or something like this). Deleting just this ampersand out of the titel block with an editor makes the file usable. I am still unshure, wether this is an kicad, Inkscape or Gimp error or even a problem of the SVG definition.
This bug is not security dangerous, but very nasty, if you do not know the simple workaround.

I have to apologize. i did not mean SVG plot, but SVG export.

The export is xml. Xml disallows some characters unless they are escaped.
& is one that must expressed as

Might be a bug in wx not kicad per se.

AFAIK the svg *export* is done with the wx print infrastructure. SVG
plots are done by the plotter classes in kicad.

So I too think that's probably a wx issue.

Bernd,

This is almost certainly a bug in wx, and one that we cannot work around other than avoiding use of that character in such a context.

The true fix would be to report it to the wxWidgets team, and get it fixed there. It is not a critical bug. I am marking as won't fix and not critical.

Thanks for reporting it, and if you are ambitious, you could file it with wxWidgets team and refer to this bug report in your report over there.

The svg *export* is no more done with the wx print.
Since some time the svg export uses the svg plotter.
(the wx version of svg exporter has an annoying bug for arcs)
So the bug could be in svg plotter.
(I did not yet have the time to see it)

Yes, normaly i am very carefully and using only the numbers, the letters
without special signs, a "-" and a "_" for file names. A point only to
discriminate suffixes......I do not now anymore, which devil rode me at
2010 to use an ampersand at a file name. Perhaps it was derived from a
firm name with an ampersand in....

Ok, i made some remarks about this bug at a german kicad FAQ
http://www.mikrocontroller.net/articles/KiCAD#Tipps.26Tricks_.2F_Eigenheiten_.2F_Bugs
So somebody would find clues about whats going on, if he notice this
strange behavior.

The wx librarys are C/C++ librarys i think. I do not know any C/C++. So
my reporting to the wx team would be an unintelligible stammering. I can
nothing tell about whats going on. I can only tell what happens if i use
programs at a certain way....

But you see what Mr. Charras wrote about this bug. So this has to be
proofed first. It would not be fair to blame the wx team for nothing.

Hello Jean-Pierre Charras.

Oh....

I am watching strange behavior at bitmap2component similar to bug 792399

https://bugs.launchpad.net/kicad/+bug/792399 wich is fixed since 2006.

Logos are not plotted to gerber, and some clues (people telling me
about) are pointing towards arcs.

But first i have to look for myself, whats going on. From my experience
with some problems at bitmap2component some years ago i think i remember
that bitmap2component does not use arcs. So this could not be....

Just asking that you post the url to this discussion over there. Nothing
more required of you than your time. Which is what you are asking of us.
Once they read this thread, it will get fixed and many months later it will
go away from kicad.

I am taking no further action, it is up to you.

Sorry, your interpretation of jp's remarks are corrrect and better than
mine. I just looked at the code (on my cell phone). And see the problem.

I will fix it in the morning. There's some escaping code in wx somewhere
we should be able to use.
