There was a problem hiding this comment.
This is the interesting part! Without the fix, this would have crashed instead

Let me check another debuggers on VSCode (DAP servers) |

Description
This fixes #756
DAP is JSON-based, so the state of all variables is dumped into a string that needs to be unicode. When a variable contains binary data that is NOT unicode, this breaks with:
source sequence is illegal/malformed utf-8.This patch makes sure that we can display at least part, and show the user that the data they are seeing is not exactly the one that is in memory.
Testing
I tried this in VSCode (which uses DAP), and saw:
As a side note,
vscode-ruby-debugdoesn't even try to show the variable content and just shows[Invalid encoding], which, IMO, is a worse UX.
