[dos] fix assert when system locale is set to UTF-8

Browse source 
* Recent versions of Windows can set the deafult locale to codepage 65001 (UTF-8).
* This produces an assert due to a missing entry in cp_hr_list[], so fix that.
* However, this fix alone is not enough, as a GetOEMCP() that returns 65001 means
  that any systems set to UTF-8 will fall back to codepage 437 for DOS, which is
  definitely not what we want => Add an extra call to determine the actual OEM
  codepage when UTF-8 is detected.
* Closes #1468
