Hi Olly,

thank vor your answer (and sorry not having answered before).

Your answer helped me and I think I now understand why "it does not work".

For test purpose I index one document with one string  with index_text_without_positions() (C++ API) the
string "ဝီ​ကီ​ပိ​သုံး​စွဲ​သူ​များက"
See this log: http://tmp.kiwix.org/tmp/kiwix-index.log (utf8 encoded)

But if I run "delve -r 1 /path/to/db" on the index I get following answer:
Term List for record #1: test က စ ပ မ ဝ သ  (utf8 encoded)
See the log : http://tmp.kiwix.org/tmp/delve.log

So, it seems to be clear for me why "it does not work" : my word is splitted in single lletters and a lot of
letters are removed.

Do I'm right? Do we can avoid that and index
"ဝီ​ကီ​ပိ​သုံး​စွဲ​သူ​များက" as only one word?

Regards
Emmanuel
