描述

If an input file name contains non-7bit-ASCII characters in it, Closure fails to operate.

STR:

  1. Install Closure compiler to directory "☃äö Ć € 🦠". (not mandatory, but for good measure to see if any issues arise from that)
  2. Pass an input file "☃äö Ć € 🦠.js" to Closure compiler as --externs or --js.

Results in

C:\☃em sd äö Ć € 🦠\emsdk\emscripten\main> dir äö.js
 Volume in drive C has no label.
 Volume Serial Number is 8847-8E7D

  1. Pass UTF-8 chars as output file :

研究方向
The issue is about UTF 8 file path handling on Windows. Look at the Closure Compiler's file reading code, likely in Java classes like `FileUtil` or `CommandLineRunner`. Check how file paths are converted to `File` objects; Java's `File` class uses the default encoding, which may not handle UTF 8 on Windows. Consider using `java.nio.file.Path` with proper encoding. Also verify that the compiler handles ` externs` and ` js` arguments correctly. Review any existing comments for clues (e.g., whether the problem is in the Node.js wrapper or core Java).
