Fix for #1203 Using the codepage with arduino.l4j.ini on win32

Fix for #1203.

Arduino specifies UTF-8 on arduino.l4j.ini or arduino-debug.l4j.ini. See the issue.
So before using chcp command for getting codepage, try to get the codepage from the configure.

I get clean output with this PR on following environment.

I think #1237 is better solution. I close this.

I checked again, PR #1237 specifies the code page as fixed to UTF-8, so the correct characters are output.
It isn't better when arduino.l4j.ini is changed. So I reopen this PR.
