barCodeScanner
the barCodeScanner does not recognize symbols such \u001d and returns strings like ↔0100000090876127215%JIXPdCh_a↔93dGVz. How do I get the raw data with all unrecognized symbols?

Here is an image of the top lines of a simple(ish) app.js (not using the bluetooth stuff yet - all commented out)
So no biggie as app seems to work regardless, but I'm interested in why I get it and what can be done to remove it.
Some previous questions seem related to the use of something called Jest (no idea what that is - I suppose I should look it up?)
Jest Testing React Native cannot use import statement outside of a module
Putting it here for benefit of others who may come across it.
So I'm currently uploading a website schema and it has thrown up some parsing errors in a string. The ® symbol is showing up as shown below. However, adding a backslash does not seem to work and is still throwing up an error on Google's Structured Data Testing tool.
For example:
'''"name": "What is ___Secure®?",'''
This throws up the error shown.
But even when I add a backslash as an escape character, it doesn't show properly, as shown.
What is the way out of this?
Thanks.
ART was imported from 'react-native' in the react-native-progress module.
import { Animated, ART, StyleSheet, View } from 'react-native';
I updated the module and now it imported from #react-native-community/art.
import { Surface as ARTSurface } from '#react-native-community/art';
ART is not used in the project anywhere else, yet I am still facing the same error.
Any idea what's wrong?
Error Message:
Invariant Violation: ART has been removed from React Native. It can now be installed and imported from '#react-native-community/art' instead of 'react-native'. See https://github.com/react-native-community/art.
Screenshot of the error.
By looking at your stack trace, You are using react-native-progress and this is an internal dependency of it and that's why you are facing this issue.
According to docs of react-native-progress.
https://github.com/oblador/react-native-progress/blob/master/README.md#reactart-based-components
So according to docs, you can remove it too for fixing this error.
Note: If you don't want the ReactART-based components and their dependencies, do a deep require instead: import ProgressBar from 'react-native-progress/Bar';.
So either you can avoid using these components which are ART based or try to fix them like below.
in file Circle.js, CircleSnail.js, Pie.js,
replace ART.Surface with
import {Surface} from '#react-native-community/art';
and in file Shapes/Arc.js
import {Shape, Path} from '#react-native-community/art';
and replace the same above.
Any package relies on ART will cause the issue with you , not only react-native-progress , but also packages with loaders like this react-native-loading-spinner-overlay ,
You can change this by finding another package of by fixing your imports
The Art library has been removed as of SDK 36 ,
If you need to use react-native-progress, which relies on ART, you can use the bare workflow and install #react-native-community/art, or implement your own progress indicator using Svg
UPDATE with FIX: It was a named import error. Make sure to not use {} imports when you export default components
Navigation stack with a header dropdown works on snack expo but I get a "Invariant violation: ... Check render method of ..." error when I build a simulator on CLI
I've tried adding or removing curly brackets from my imports but it's no use. I suspect it might be something about withNavigation exports in the components or import/exports in the navigation stack

Does anyone know what is going on here?
It was a named import error. Make sure to mostly not use {} imports on components
Im trying to work with text and im following a tutorial that says in order to work with text just type this
var React = require('react');
var Text = React.Text;
and then you can use it and it works with him
but with me it did not work and gives error says
element type is invalid expected a string
and in order to make it work i wrote
import {Text} from 'react-native';
so why is this difference?
i think that the first one familiar to me than the second one
You are searching in two different places. In the first attempt you are looking inside the react package, which is the same one you would use for React on the web. Of course, it does not make much sense having a React Native-specific component in that package, and that is the reason why you are not finding it. In the second one, you are querying a completely different package, the react-native one, which does have the element you are looking for.
