many MS installer use Unicode file streams to write their log files.
Bug 8598 is about general unicode support for CRT functions.

IE9 installer for example spams console due to fopen() not recognizing
",ccs=xxx" sequence in mode string.

Bug 8598 needs proper implementation first to really support this but in the
