How to escape characters in Pango markup?
Question
My program has a gtk.TreeView
which displays a gtk.ListStore
. The gtk.ListStore
contains strings like this:
"<span size='medium'><b>"+site_title+"</b></span>"+"\n"+URL
Where URL
is (obviously) a URL string. Sometimes there are characters in URL
that cause pango to fail to parse the markup.
Is there a way to escape URL
as a whole so that pango will just ignore it so it will be displayed literally? If not, how should I "escape" special characters in URLs?
Solution
You need to escape the values. I'm not sure what exact format Pango requires, but it looks like HTML and the cgi.escape function may be all you need.
import cgi
print "<span size='medium'><b>%s</b></span>\n%s" %
(cgi.escape(site_title), cgi.escape(URL))
OTHER TIPS
glib.markup_escape_text
may be a more canonical approach when using GTK.
