@IvanGoncharov could you have look at the failing coverage tests and give me a hint how to fix them? thanks |

this looks awesome @andimarek! I think it wants you to add a test case for this exception (notice the lines highlighted in red): |

thanks a lot @acao for the hint 👍 ... now the build is green. |

I just updated this to reflect the latest changes in graphql/graphql-spec#849

* Requires surrogate pairs, regardless of if they are escaped * Support braced unicode escapes * Improved error messages with more tests

There was a problem hiding this comment.
I don't trust Unicode symbols in tests, because you can't visually inspect that codes are matching.
Can we use JS escape sequences instead?

Actually, I wrote a simple ESLint rule to find non-ASCII characters in #3053
And discovered that my editor (NeoVim) use strange encoding for ⏱️ emoji:

Depends on #3115 Implements RFC at graphql/graphql-spec#849. * Replaces `isSourceCharacter` with `isUnicodeScalarValue` * Adds `isSupplementaryCodePoint`, used in String, BlockStrings, and Comments to ensure correct lexing of JavaScript's UTF-16 source. * Updates `printCodePointAt` to correctly print supplementary code points. * Adds variable-width Unicode escape sequences * Adds explicit support for legacy JSON-style fixed-width Unicode escape sequence surrogate pairs. * Adds `printString` to no longer rely on `JSON.stringify`. Borrows some implementation details from Node.js internals for string printing. Implements: > When producing a {StringValue}, implementations should use escape sequences to > represent non-printable control characters (U+0000 to U+001F and U+007F to > U+009F). Other escape sequences are not necessary, however an implementation may > use escape sequences to represent any other range of code points.

This is the complementary implementation for the proposed spec change graphql/graphql-spec#687.
Most notably full unicode is already supported today, albeit without having explicit tests for it. (It is fully supported because the lexer never checks that the actual unicode code point is <=0xFFFF as required by the spec)
The only new code that is added is the verification of the surrogate pairs. The current implementation allows for invalid surrogate pairs.
