In SAS 9.4M5 in Windows 10 64-bit the following gives unparsable SVG graphics:
options colophon="© Company";
ods html5 device=svg options(svg_mode='img');
/* some graphics output */
What you find in the *.svg file is a line like this between desc and defs (line 4):
<!-- © Company -->
In the HTML page which refers to this you may see a broken link symbol or nothing. If you open the SVG file in a browser you may see nothing. If you are lucky (e.g. using Firefox) you will see a parse error message.
I have not tried this with embedded SVG because I need a separate img file.
A workaround is to replace the copyright symbol © with plain ASCII (c) or the word "copyright".
@Sas Please could you fix this minor bug which is very difficult to diagnose.
