Known Issues with Character Encoding

tv_grab_ch_search data source sends windows-1252 as iso-8859-1 (e.g. Euro Symbol) Newer HTML readers are supposed to handle this correctly. Need to verify that we can dump perl strings at XMLTV::Writer and it will do the right thing with regard to escaping anything outside $encoding into XML entities.
tv_grab_se_swedb fix commited upstream
#1910245 should add a test for HTML entities in the generated XML. (hint ´ is invalid XML!)

Issues with Time Zones

Feel free to take anything from the list

#1880681 the bug was solved (not a bug), the suggestion for Supplementary Files is turning one can of worms into another...
tv_grab_huro has no maintainer?
- #2748362 site changes: holes in the collected programs
- #2837668 site changes: unexpected hash references
- #2858285 close it, was "no channels found", the grabber does not fail completely anymore (see status)
- #2910015 close it, was "no programs on channel 1", test_grabbers tests with that channel succesful

remove group/status/category examples from the tracker (might check for other unused stuff while there)

Maybe it's best to move most uses over to our own Get_nice.
