md5Digest gives different results Mac vs Windows LC 9.5.1

[Bill Vlahos]

The LiveCode Dictionary states:
When generating a messageDigest for a string, it is a good idea to encode it to binary data using the textEncode <> function. Otherwise, the messageDigest could be different, depending on the platform <> on which your application is running.

However, I tried their example in the Dictionary but it still gives different values on Macintosh vs. Windows:
put textEncode("My very large data", "UTF-8") into tOriginal
put messageDigest(tOriginal, "SHA3-256") into tChecksum

Why would the platform calculate the hashes differently?
Why did older versions of LiveCode calculate it the same?

Regards,
Bill Vlahos
