Saxon » SaxonJS

I thought I had reported a problem for Saxon JS 2.0: when I run e.g. xslt3 -s:input.xml -xsl:sheet.xsl -t on Windows where I am in a directory that contains a space in the path (e.g. C:\Users\John Doe\folder\subfolder) with 2.0 and still with 2.1 I get an error that indicates that the source is failing to be loaded from C:/Users/John%20/Doe/folder/subfolder/input.xml (note the percentage encoding of the space) e.g.

Saxon-JS 2.1 from Saxonica Node.js version v12.18.0 Compiling stylesheet C:\Users\John Doe\folder\subfolder\sheet.xsl Stylesheet compilation time: 0.199s Transformation failed: Error SXJS0006 Failed to read XML source input (Failed to read C:/Users/John%20/Doe/folder/subfolder/input.xml(no such file))

So it appears the relative stylesheet URI (or is Saxon JS only treating that option as a file name?) works fine but the relative input URI fails.

https://saxonica.plan.io/issues/4590 is kind of related although that is an output URI not an input URI.
