[03:02:37] <itsmoon>	 I'm building a JS tool and I need to know if it's safe to assume that no mediawiki filenames will ever contain the characters : or | (vertical bar). Are these two guaranteed to be disallowed on all wikis by technical limitations
[03:02:50] <itsmoon>	 ?
[03:05:20] <itsmoon>	 I am assuming "|" is disallowed, otherwise [[File:example.jpg|thumb|caption]] would not work properly
[03:10:26] <itsmoon>	 But what about [[File:W:/2016ALBUM/.svg]] for example
[03:11:10] <itsmoon>	 Are those technically disallowed or just discouraged
[03:23:11] <itsmoon>	 There is https://en.wikipedia.org/wiki/Help!:_A_Day_in_the_Life for example
[03:27:06] <itsmoon>	 And https://en.wikipedia.org/wiki/Escherichia_coli_O157:H7
[03:27:40] <itsmoon>	 But unsure for filenames
[06:24:29] <p858snake|cloud>	 itsmoon: it's deprecated but https://www.mediawiki.org/wiki/Manual:$wgIllegalFileChars is probably the best reference
[06:50:12] <itsmoon>	 p858snake|cloud : gotcha thanks
