That's because you aren't controlling the string encoding.

What is "normal"?

What is the native platform encoding on the server side?

Always include encoding explicitly in the calls to encode/decode strings.

Don't manipulate bytes to make Strings. Even 'char' isn't safe, as code points can be wider than 16 bits.

Don't hard-code numeric values for end-of-line.

Use a 'Reader' and 'Writer' instead of raw streams.

Spell "receive" correctly.
