Using contextual filters on taxonomy terms doesn't work if the translated term has capital letters

Creating a view that uses contextual filters to get translated taxonomy term names (Validator: Taxonomy term (i18n), Filter value type: Localised Term name/synonym converted to Term D) doesn't work as expected when the translated term has capital letters. For example given the terms with their translations:

Books (Livres)
Music (Musique)

ans a view with path /myview/(termname)

/myview/Books (works)
/myview/books (works)
/myview/Livres (works)
/myview/livres (doesn't work)

To solve the problem, the query in i18nviews.module -> function i18nviews_locale_source() needs to make a case insensitive comparison using CONVERT(lt.translation USING utf8). So the query should be:

  $select->innerJoin('locales_target', 'lt', '(ls.lid = lt.lid AND CONVERT(lt.translation USING utf8) = :translation AND lt.language = :language AND ls.textgroup = :textgroup )', array(

This way, the lowercase url will now work as expected on capitalized term names.
