Convert shapefile to geoJSON via a web browser without Server-Side code. This conversion will unzip your file and reproject the data with correct encoding in JavaScript.
Caused by proj4js/proj4js#143
Since this issue has not been solved yet, I suggest a workaround that just stopping loading the projection file and prompting a message like 'Unsupported Projection: EPSGUSER'.
Will send a PR later.
