to_html()没有encoding参数？造成输出中文显示乱码

[645187919]

Code Sample, a copy-pastable example if possible

# Your code here
data = pd.read_csv("test.csv",encoding="gbk")
print(data)
html = data.to_html(col_space=40,justify="center")

Problem description

当我用to_html（）方法生成html的时候，中文显示乱码，后来一看该方法竟然没有encoding参数，希望作者能完善了，这样以后会方便很多人哈！

@645187919 Thanks for the report, however, can you provide a reproducible example. http://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports

I think he is saying there is no encoding argument in to_html, and this will cause an issue when exporting contents including Chinese characters. @simonjayhawkins

[simonjayhawkins]

Thanks @charlesdong1991 .

the to_html method has no encoding. I assume that it is fairly simple to work-around by passing an open buffer with the correct encoding or not passing a filepath, and writing the return unicode string to file using the appropriate encoding?

the buffer handling code is shared with to_latex and to_string.

to_latex already has an encoding parameter and the shared code can handle encoding.

so it should be straightforward to add encoding to to_html ( and to_string) for consistency.

#15008 (comment) "Textual payloads should support the encoding argument"

#28377 has been opened for discussion regarding passing options for the open call.

but I think in this case, for consistency with other IO methods, we could just add the encoding argument directly to the to_html argument list. @TomAugspurger

[charlesdong1991]

yeah, agree, a solution to solve this issue could be adding encoding to to_html in io/formats/format.py @simonjayhawkins
And a separate PR could be making it sharable among those three methods.
