DITA-OT 3.6 or above can't handle Input file of non-ASCII path.
## Expected Behavior
<!-- If you're describing a bug, tell us what should happen. -->
Input file of non-ASCII path should be processed properly.

## Actual Behavior
<!-- Tell us what happens instead of the expected behavior. -->
When the full path of input file contains non-ASCII characters, a fatal error occurs.
This behavior depends on DITA-OT version.

- 3.7.2 -> Failed
- 3.6.1 -> Failed
- 3.5.4 -> Success

## Possible Solution
<!-- Optional suggestions on how to fix the issue, or implement the changes. -->
<!-- If you know how to fix the issue, please create a pull request instead. -->
Probably the direct cause of this error is the encoding of .job.xml file created in Temp directory.
The encoding of .job.xml file is Shift-JIS which is the default encoding of Japanese environment.

## Steps to Reproduce
<!-- Test case, Gist, set of files or steps required to reproduce the issue. -->

1. Unzip the following sample to some directory.
2. run dita command `dita.bat -i .\\サンプル\\hierarchy.ditamap -f pdf`

<!-- Create a Gist via <https://gist.github.com/> to upload your test files. -->
<!-- Link to the Gist from the issue or attach a .zip archive of your files. -->

## Copy of the error message, log file or stack trace
<!-- Long logs should be attached or in linked Gists, not in the issue body. -->
