Questions on POLE library (and HancomWord support)

[Park Shinjo]

Unfortunately the documentation is in Korean[1] (about 460 pages), we need
translation of the document in English. Some of developers also criticized
details of specification document, since some part of spec does not match
with actual implementation and some parts are missing in the document.

The downloaded file is zipped, and its file name is encoded into EUC-KR.
You need to unzip this file with proper encoding support.
