Walkthrough

Updates a single unit test to convert a JSON string to a byte array using explicit UTF-8 encoding instead of the platform default, by adding a StandardCharsets import and modifying the getBytes() call.

Changes

Test byte conversion fix

Layer / File(s)	Summary
UTF-8 charset usage in byte array test base/src/test/java/com/tinyengine/it/common/utils/JsonUtilsTest.java	Adds StandardCharsets import and changes testDecode_ByteArray to use json.getBytes(StandardCharsets.UTF_8) instead of json.getBytes().

Estimated code review effort: 1 (Trivial) | ~2 minutes

Poem

A hop, a byte, a charset true,
UTF-8 now shines anew,
No platform quirks to lead astray,
Just clean encoded bytes today. 🐇✨
