What if my hex string has spaces or 0x prefix?

DevDash automatically strips common prefixes (0x) and whitespace before decoding.

Why do I get garbled output?

If the hex string does not represent valid UTF-8 text, the decoded output may contain replacement characters or unexpected symbols.

No. Hex digits a-f and A-F are interchangeable. Both 4a and 4A decode to the letter "J".
