+### What if my utf-8 data is decoded incorrectly?
+
+`stream-json` does not decode utf-8 relying on Node to do it correctly. Apparently in some cases Node can fail to decode multi-byte characters correctly, when they are split between different buffers. If you encounter that problem (I did not see it in the wild yet), you can solve it by piping an input stream through a sanitizer before sending it to `stream-json` parser. These two packages look promising, and appear to be doing the right thing:
