Does not open articles with special characters

[Popolechien]

Tested on Wikivoyage Europe (latest zim 2018-06-10) and Kiwix-Android 2.4 Build 1180980:

When searching for an article I can not open those with special characters (Saint-Lô, Zürich, Korčula): they are found in search, even without typing ô, ü or č, but clicking/tapping the name in the search list will return to the previously opened article.

@mhutti1 I confirm this regression with http://mirror.download.kiwix.org/zim/wikivoyage/wikivoyage_en_europe_2018-06.zim :(

Seems to be related to #594

Root cause is #765 but I am going to implement a quick fix here.

[mhutti1]

Done some research and I think implementing #765 is necessary to catch all possible versions of this but will require database changes and upgrade.

Ok FWIW it doesn't work with Chinese characters either.

@mhutti1 I do not think you have do to so because (1) This was working fine, we have a regression here (2) kiwix-serve works that way too, and it works fine

@kelson42 Ok I have come up with a fix that should work but we should implement #765 for 3.0

@mhutti1 thx, yes we should use urls instead of titles
