I want to use a password containing symbols for my sbt proxy settings

I installed sbt because I wanted to use scala on my company PC, but when I tried sbt new, I couldn't get the plug-in.

I found a way to configure proxy settings in Qiita, so I tried it, but it didn't work.

sbt/activator proxy settings (v0.13.9/v1.3.7) - Qiita

The reason is that the proxy password is +-[]I think it's because I'm using a symbol that contains {}(), but I don't know how to escape these special characters in sbtconfig.txt.
How do you deal with special characters in the argument given to jvm?
Also, I would appreciate it if you could let me know if there are any pages that describe the handling of such special characters.

Add ---

The sbtconfig.txt configuration is as follows:

#Set the java args to high
-Dfile.encoding=UTF-8
...abbreviated...
- Dhttp.proxyHost=****.****.local
- Dhttp.proxyPassword="hoge{}<>()[]+-Password"
- Dhttp.proxyPort=****
- Dhttp.nonProxyHosts="localhost|127.0.0.1"
- Dhttps.proxyHost=****.****.local
- Dhttps.proxyPassword="hoge{}<>()[]+-Password"
- Dhttps.proxyPort=****
- Dhttps.nonProxyHosts="localhost|127.0.0.1"

When I saw the communication in Wireshark, it looked like this:

CONNECT repo1.maven.org:443 HTTP/1.1
User-Agent: Java/1.8.0_****
Host: repo1.maven.org
Accept: text/html, ... abbreviated...
Proxy-Connection:keep-alive

HTTP/1.1407 Proxy Authentication Required
...abbreviated...
X-Squid-Error: ERR_CACHE_ACCESS_DENIED
...abbreviated...

After a lot of research, I found information that Windows might not be using sbtconfig.txt.

However, I am currently struggling to figure out how to fix it...
