Revert "Resolves: #i63015# always default to WinAnsiEncoding..."

Because under Linux use text
"'"
and font "Nimbus Sans L"
and export as pdf and the output is garbled

If we do want to stick WinAnsiEncoding here then we'll presumably have have to
test that pEncoding actually matches WinAnsiEncoding and/or generate an
additional Encoding/Differences from WinAnsiEncoding for that font.

This reverts commit eea16cb3e65a4308caddb7618d31a76ca259dbb1.
