CharsetNativeKt.platformUtf16 inaccessible outside main thread on native

[fluidsonic]

platformUtf16 is only accessible on the main thread because it is not marked as @SharedImmutable. That breaks String.toByteArray().

This also breaks Ktor HttpClient on non-main threads (TextContent.bytes).

private val platformUtf16: String by lazy { if (ByteOrder.nativeOrder() == ByteOrder.BIG_ENDIAN) "UTF-16BE" else "UTF-16LE" }

We're rebooting the kotlinx-io development (see #131), all issues related to the previous versions will be closed. Consider reopening it if the issue remains (or the feature is still missing) in a new version.
