Specific core mask is displayed incorrectly on PJS apps

  Bug report

• What is the current behavior and expected behavior?
  An incorrect core mask was reported in Incorrect core mask on coretime-rococo paritytech/polkadot-sdk#3614
  More details on the issue.

It was pointed out that this is just an incorrect representation of the core mask b01010101010101010101010101010101010101010101010101010101010101010101010101010101, which equates to UUUUUUUUUU in Unicode.
When a region is interlaced 50% we end up with this core mask. This will happen quite often and should be displayed in a way that is consistent with any other core mask.

It appears that apps tries to decode it as UTF-8 before (correctly) decoding it as hex or an 80 bit binary string. It should not try to decode this field as UTF-8.

• Please tell us about your environment:
  Easily reproduced by checking the Rococo Coretime Chain state broker.regions and ctrl+F UUUUUUUUUU, comparing to the other regions and how they are displayed.

  • Version:
    Polkadot parachain v4.0.0
    api v10.11.2
    apps v0.133.2-119

  • Environment:
    Browser

This issue is related to the PJS API repository, as it arises during the attempt to format regionId using toHuman()

Maybe a code owner could move this issue to that repo

This is in the queue to check further on Thursday! Thanks for the patience.

So I looked into this (not to deep as its been a long day). But the console is logging:

params: initValue: No default value for type PalletBrokerCoreMask from {"info":10,"name":"mask","type":"PalletBrokerCoreMask"}, using defaults

params: findComponent: No pre-defined component for type PalletBrokerCoreMask from Plain: {"info":10,"name":"mask","type":"PalletBrokerCoreMask"}

Which is a good start. I'll continue looking into this in the morning.

Ahh nvm the above warnings i posted have to do with the params.... Not connected to the above issue.

Sorry for the little delay. This is a bit deeper than I thought, but it goes all the way to the common repo. Basically the storage key for mask is valid ascii which is interpreted in the api as that here.

Looking into a more specific solution now.
