During testing, it became evident that the occurrence of the error described in issue #55773 is influenced by the character encoding used by the user. For instance, users working with CP1252 are unlikely to encounter any errors, regardless of the characters they use. In contrast, users with encodings like CP932 are more prone to experiencing errors. Take the character "月" as an example, which is represented in UTF-8 as: E6 9C 88 In CP932, the byte 88 is interpreted as the leading byte of a 2-byte character, potentially causing issues. The key takeaway is that to ensure accurate regression testing, it might be necessary to test the runtime environment with character encodings other than CP1252. I also looked for other tests that might include regression testing against Windows-specific character encodings but couldn’t find any. If you have any good ideas, I’d appreciate your input.

From what I understand, you’re looking for something along these lines: const stdoutExec = execSync('@chcp 932 >nul & \"' + process.execPath + '\" \"' + nonAsciiPath + '\"', { encoding: 'utf8'}); assert.strictEqual(stdoutExec, 'check non-ascii\n'); However, I wanted to point out that this code does not fail when run on the main branch on my local machine. Because of this, it might not be ideal to use this approach directly without further investigation.

I tried it as well, and it seems that the behavior was not affected. It appears that we need to change the system's character encoding rather than just the console's encoding. For instance, the following minimal C++ code reproduces the same error: int main() { std::string path = "\x88"; std::filesystem::path file(path); } This code alone triggers the same issue.

I am currently investigating whether it is possible to change the system's character encoding within a cctest.
