• What is the current behavior?
  I Tried to export a plot_data html to stream with Figure.to_html_stream with a StringFile from dessia_common

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem Avoid reference to other packages

I generated a plot_data.core.PrimitiveGroup and applied:
from dessia_common.files import StringFile
stream1 = StringFile('test')
primitive_group.to_html_stream(stream1)

I have the following error:

File "c:\users\mack\documents\git\plot_data\plot_data\core.py", line 138, in to_html_stream
    stream.write(html.encode('utf-8'))

TypeError: string argument expected, got 'bytes'

New information 30/01/2024:
with BinaryFile it works well.

• What is the expected behavior?
  Have the html written in the stream.

• What is the motivation / use case for changing the behavior?
  Customer

• Possible fixes
  encode('utf-8')
  transform string in octet, perhaps change it ?
