 - The issue comes from the fact there are special Unicode characters which
 occupy in Unicode a character but in UTF-8 3/4 characters.
 sqlite engine handle only UTF-8 strings (including file names) and inside
 the
 engine converts UTF-8 path to Unicode (in Windows side) but the problem is
 all
 buffers allocated gets allocated as maximum 260 characters. This leads to
 the
 fact in some cases file name gets trimmed to 260 characters failing to
 open the
 file.
  The fix was to increase the space allocated in Windows side to 4*MAX_PATH
 to be
 able to handle some UTF-8 characters which occupies more than on byte.
