save_graph_shapefile no encoding option

[raphadasilva]

Good morning !

I don't know if it's the right place to make this observation, I apologize by advance if it's not. Here's my point : I used OSMnx to display the street network of Liège (Belgium).

import osmnx as ox, matplotlib.pyplot as plt

liege_streets = ox.graph_from_place('Liège, Belgique', network_type='walk', retain_all=True)
liege_streets = ox.project_graph(liege_streets)

fig, ax = ox.plot_graph(liege_streets, fig_height=10, show=False, node_size=0, close=False, edge_color='#777777')

plt.show

This works perfectly fine, with this nice view of Liège :

Then, I wanted to save this network in shapefile format. My goal was to achieve a merge with another lib', so I used the command :
ox.save_graph_shapefile(liege_streets, filename='liege_streets')

But there was this message :
WARNING:Fiona:CPLE_AppDefined in b"One or several characters couldn't be converted correctly from UTF-8 to ISO-8859-1.\nThis warning will not be emitted anymore."

I'm stuck because I would keep the UTF-8 encoding (because my other database is encoded with UTF-8). I read the code of save_graph_shapefile function and found no argument refering to the file's encoding. Do you think I must use Fiona library to do that ?

Thanks in advance and have a nice day !

Good point. I think geopandas has an encoding argument that I can propagate to the save_graph_shapefile() function. I'll add this to the next release.
