Re: [Discussion] Proposal: grapheme_mask() helper function

Hi Nick, Ilija, and everyone, Thank you for the quick feedback, Nick! I completely agree with your suggestion. Having both str_mask() for general byte-based masking and grapheme_mask() for Unicode-aware operations is the perfect approach to cover all use cases in PHP. I have already prepared the implementation, stubs, and tests for grapheme_mask. Regarding your suggestion, I’m more than happy to work on str_mask as well and include both in the proposal. However, I'm currently facing a technical issue with the PHP Wiki. My account (sepehrphp) seems to be inactive or pending activation, which is preventing me from logging in and publishing the RFC. @Ilija, could you please check my account status? As soon as the login issue is resolved, I will post the RFC covering both functions so we can discuss the implementation details there.
