It looks like webread includes a subcommand to reencode the URL. Maybe there is some option to stop it from doing that?
How do I stop webread from converting "%2B" into "+"?

I need MATLAB to run webread with this exact URL: https://s3.amazonaws.com/appforest_uf/f1620499445726x864228122125595900/JBL%20VRX932LAP%20PSHF%2B3dB%20-%202m%20-%207150%20142.csv
Unforunately, every time it webread runs it converts the all of the "%2B" into "+" and then returns an error. How do I get it to use the exact URL as entered???
It keeps returning this error:
Error using matlab.internal.webservices.HTTPConnector/copyContentToFile (line 389)
The server returned the status 403 with message "Forbidden" in response to the request to URL
https://s3.amazonaws.com/appforest_uf/f1620499445726x864228122125595900/JBL%20VRX932LAP%20PSHF+3dB%20-%202m%20-%207150%20142.csv.
Error in readContentFromWebService (line 62)
copyContentToFile(connection, filename);
Error in webread (line 125)
[varargout{1:nargout}] = readContentFromWebService(connection, options);
Here's my code:
TF = webread('https://s3.amazonaws.com/appforest_uf/f1620499445726x864228122125595900/JBL%20VRX932LAP%20PSHF%2B3dB%20-%202m%20-%207150%20142.csv')

There isn't any command that I'm aware of. The idea is to replace every character with a value above 255 (or with a special meaning) by its hexadecimal version. So '+' becomes '%2B'. Since webread parses your URL for these changes, you can double-encode them: use '%252B' instead.
The idea is that webread parses the '%25' to a percent symbol and leaves the rest as is.
I have not tested this idea.
