Unsupported unicode chars

[Excustic]

Apparently remarkable uses \u2028 and \u2029 as their line separators in some text blocks. This seems to break the svg exporter when trying to append the html output.

  File "D:\Work\remarkable\tests\Lines2InkML\venv\Lib\site-packages\rmc\cli.py", line 137, in convert_rm
    tree_to_svg(tree, fout)
  File "D:\Work\remarkable\tests\Lines2InkML\venv\Lib\site-packages\rmc\exporters\svg.py", line 103, in tree_to_svg
    draw_text(tree.root_text, output)
  File "D:\Work\remarkable\tests\Lines2InkML\venv\Lib\site-packages\rmc\exporters\svg.py", line 291, in draw_text
    output.write(f'\t\t\t<text x="{xx(xpos)}" y="{yy(ypos)}" class="{cls}">{str(p).strip()}</text>\n')
  File "C:\Python312\Lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Quick fix
I am bypassing this error in my forked version by just doing this:

# Translate unsupported unicode chars
content = str(p).replace('\u2028', '<br>').replace('\u2029', '<br>')

But maybe there should be a function that handles and parses correctly all special Unicode characters.
