I noticed today when importing a list from a UTF-8 text file that AWB now capitalizes the first letters of all imported terms (e.g. the list has "foo" but AWB imports this as "Foo"), even when I set the wiki to en.wiktionary, where case matters and most entries are not capitalized. (If I import e.g. the contents of a category, they are imported as expected, without erroneous capitalization.) The issue persists even after I updated to version 6.5.0.0.
The older, expected, and desired behavior would be for it to import the list without changing it, i.e. import "foo" as "foo".
(It looks like the same problem occurred and was fixed at least once before in the distant past, if knowing @Rjwilmsi 's old 2010 fix helps anyone fix it again.)
