        "typescript",
        monaco.Uri.parse("root")
    )
});

monaco.languages.typescript.typescriptDefaults.setCompilerOptions({
  ...monaco.languages.typescript.typescriptDefaults.getCompilerOptions(),
  moduleResolution: monaco.languages.typescript.ModuleResolutionKind.Classic
});

const parsed = monaco.Uri.parse("/test.ts?id=123");
monaco.editor.createModel(
    "export const X = 1;", 
    "javascript",
    parsed
);
console.log(parsed)

Reproduction Steps

Actual (Problematic) Behavior

There's an error caused by adding query param (with equal sign or Russian word as example) to URI. The problem is in method getValidSourceFile. This file exists in the list of models, I checked this via program.getSourceFiles(), but its fileName doesn't correspond due to encoding equal sign to %3D, so the method returns undefined and console shows this error:

Uncaught (in promise) Error: Could not find source file: 'file:///test.ts?id%3D123'. at Ve (/vs/language/typescript/tsWorker.js:255:8493) at Object.On [as getSyntacticDiagnostics] (/vs/language/typescript/tsWorker.js:255:13349) at lm.getSyntacticDiagnostics (/vs/language/typescript/tsWorker.js:33955:2559) at S.fmr (workerMain.js:22:33695) at f._handleMessage (workerMain.js:22:17684) at Object.handleMessage (workerMain.js:22:17309) at w._handleRequestMessage (workerMain.js:22:14120) at w._handleMessage (workerMain.js:22:13570) at w.handleMessage (workerMain.js:22:13458) at f.onmessage (workerMain.js:22:17401)

Expected Behavior

File should be returned from the list of model regardless encoding/decoding issues in URI.
