I greatly appreciate your help! Thanks!
There are two parameters in Apache config file that tell it to add a
charset field by default. They are: AddDefaultCharset and
AddDefaultCharsetName. The first one should be set to off to prevent
Apache from replying with a charset field set after the content type.
After disabling AddDefaultCharset htdig worked as expected.
