When does this happen?

IF When using Langfuse (self-hosted) with non-ASCII text (e.g., Vietnamese), the Tracing Input/Output tables display Unicode escape sequences instead of the actual characters.

How others solved it

THEN To read the actual text, copy the escaped string and decode it externally, e.g., using `JSON.parse('"\\uXXXX"')` in a browser console or an online Unicode decoder. The detailed trace view may show the correct text. This is a known bug in Langfuse v3.97.2; there is no built-in fix. Monitor future releases for a permanent resolution.
