... I wanted to spot as well that
force_unicode is in the doc but is not available.
TypeError: to_html() got an unexpected keyword argument 'force_unicode'

@wesm Had a quick look at this.

Currently DataFrame.to_string() and DataFrame.to_html() have the same docstring (through Appender decorator), except for bold_rows. However to_html() misses justify and force_unicode arguments. It probably makes sense for html not to add the force_unicode argument and always use unicode.

By the way bold_rows=True also makes the column labels bold.

@lodagro appear to have gotten this one. I think the headers always come through as bold via <th> but I could be wrong. I was doing a bunch of other unicode cleanup / fixes in #795 also.
