UTF-8 BOM causes error
thehappycheese opened this issue · 1 comments
Description
Opening a UTF-8 file containing a byte order mark (BOM) causes an error and the map viewer fails to load.
Reproduce
- Try to open a UTF-8
.geojsonfile file starting with binary 0xFEFF (The UTF-8 Byte Order Mark or BOM). - A popup appears reading
Renderer Failure: new ims export features.geojson. Unexpected token in JSON at position 0See screenshot below:
Also note in the above screenshot that Jupyter's text editor also incorrectly shows the BOM as a red dot. Opening the same .geojson file in VS Code works as expected; the the BOM is hidden.
Context
- Operating System and version: Windows 10
- Python Version: 3.9
- Browser and version: Chrome
- JupyterLab version: 3.0.16
The troublesome geojson file is the result of an export from an ESRI Web AppBuilder application.
