Winwdows solr post - Invalid UTF-8 middle byte 0xe3 (at char #10, byte #-1)

问题

My code c2020 is running and available what I visit http://localhost:8983/solr/#/c2020/query.

Locally, when I try to run:

solr-7.7.2> java -jar -Dc=c2020 example\exampledocs\post.jar "C:\temp\path_to\a_doc.pdf"

I get:

SimplePostTool version 5.0.0

POSTing file A Half Century of Macro Momentum_vf.pdf to [base]

Now, if I run:

java -Durl=http://localhost:8983/solr/c2020/update/extract -jar example\exampledocs\post.jar "C:\temp\path_to\a_doc.pdf"

It works:

SimplePostTool version 5.0.0
Posting files to [base] url http://localhost:8983/solr/c2020/update/extract using content-type application/xml...
POSTing file a_doc.pdf to [base]
1 files indexed.
COMMITting Solr index changes to http://localhost:8983/solr/c2020/update/extract...
Time spent: 0:00:14.647

But it does not send all "fields" I want to see such as the file path or the file name.

I'd like to get the raw post doc to work if anyone could advise.
