Description Wolfram Schmied 2009-12-06 00:59:09 UTC See http://en.wikisource.org/w/index.php?title=Index_talk:1965_FBI_monograph_on_Nation_of_Islam.djvu&oldid=1678252#Non-printables_in_OCR_output I don't know how much of a security concern that is, but I think DELs and somesuch do not belong in source code, and should be stripped automatically. Comment 1 Dan Wolff 2012-12-19 08:32:24 UTC Yeah, it seems like invisible characters are allowed in wikitext for no good reason. E.g. here[1] I'm cleaning up a left-over LTR character, since my script gave weird results because of it.
