Summary The URL Pattern API allows developers to specify pattern strings. Those are transformed to regular expressions internally. When the API was first implemented, these regular expressions were compiled with the u flag. We're going to update it to the v flag, enabling Unicode sets <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/unicodeSets> . Blink componentBlink>URLPattern <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EURLPattern> TAG reviewNone TAG review statusNot applicable Risks Interoperability and Compatibility https://github.com/tc39/proposal-regexp-v-flag#how-is-the-v-flag-different-from-the-u-flag This doc has a list the potentially breaking changes between u and v. Some patterns that previously would compile, now throw an error with the v flag, specifically those with a character class including either an unescaped special character or a double punctuator. I believe it does not significantly affect the patterns in use today. From UMA metric on Beta, incompatible patterns are less than 0.001% of the total compilation. Also, the use counter of the API itself has only 0.11%. The expected impact is extremely limited. *Gecko*: No signal *WebKit*: No signal *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
