Error when update data to Windows client

[qu123xxx]

when I update this data

Geometry
——————
TEXT("你好",2,121 -69)

to a layer in Windows client use WWTLayer.update(), I encounter the following Error：

`UnicodeEncodeError: 'latin-1' codec can't encode characters in position 311-312: Body ('你好') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

But it's OK when I use English data.

Geometry
———————
TEXT("hello",2,121 -69)
`

I try to modified the updat function in 'Lib\site-packages\pywwt\windows\layer.py'

u = requests.post(self.wwt.wwt_url, params=params, data=data_string)
to
u = requests.post(self.wwt.wwt_url, params=params, data=data_string.encode('utf-8'))
Then run my code. It will stuck for a while and encounter another Error：

[pkgw]

It looks like your change to pywwt is the correct one to make.

After you have done that, I suspect that WWT's internal code is unable to handle the Chinese characters in your text overlay, which is causing an error that causes it to close the connection to your Python program.

If you are able to launch WWT with logging enabled, you may be able to get some more information about where exactly the problem is. But this might require a debugger to figure out.

Thanks for your reply. I will try it later.
