Fix creation of Uri if the lookup key has characters that are not allowed in a Uri

                if (mAllRestricted) return false;

                // TODO: Keep around actual LOOKUP_KEY, or formalize method of extracting

                final String lookupKey = mLookupUri.getPathSegments().get(2);

                final String lookupKey = Uri.encode(mLookupUri.getPathSegments().get(2));

                final Uri shareUri = Uri.withAppendedPath(Contacts.CONTENT_VCARD_URI, lookupKey);

                final Intent intent = new Intent(Intent.ACTION_SEND);
