At first glance it appears there is no support for ISO-8859-1.
Looking at the libharu source code (src/hpdf_encoding.c) you can see that
what they call 'WinAnsiEncoding' is Windows Code Page 1252. CP1252 is a superset of ISO-8859-1 that adds printable characters at 0x80 to 0x9F.
So you can use that to get ISO-8859-1.
