Path normalization can fail on windows

[samhill303]

Before you start

• I searched the existing issues (including closed ones) and didn't find this one.
• I'm using a currently released version of this project.

Summary

The fixSlashes function doesn't account for a mix of / and \ which may be valid for a path on windows. This appears to not generally cause an issue beyond failing tests, but there are likely edge cases to check

Steps to reproduce

Run windows tests without ignoring path tests

Expected result

All valid paths should be correctly handled, and tests should match the behavior

Actual result

Tests are failing

Affected platforms

• Android
• iOS
• macOS
• watchOS / tvOS
• JVM
• JS / Wasm
• Linux / Windows (native)
• Not platform specific
• Build / Gradle plugin only

Version

1.4.0

Environment

No response

Logs, stack traces, or build output

Possible cause or fix

We could consider moving our path concatenation and slash fixing logic over to kotlin.io's path class
