[Bug]: Storybook7 corrupted unicode

[byhhh2]

Describe the bug

I'm using Storybook 7 with MDX to create stories In some cases, when Unicode text is injected as props, the Unicode characters appear corrupted on the screen This issue occurs only in the local env

import { Meta, Canvas, Story } from "@storybook/addon-docs"

<Meta title="UnicodeCase" />

### Case1

<Canvas>
  <Story name="case1">
    {() => {
      return <div>👍</div>
    }}
  </Story>
</Canvas>

### Case 2 💀

export const Case2 = ({ text }) => {
  return <div>{text}</div>
}

<Canvas>
  <Story name="case2">
    {() => {
      return <Case2 text="🤔" />
    }}
  </Story>
</Canvas>

### Case 3

export const Case3 = () => {
  return <Case2 text="😇" />
}

<Canvas>
  <Story name="case3">{Case3.bind()}</Story>
</Canvas>

### Case 4

export const Case4 = ({ comp }) => {
  return <div>{comp}</div>
}

<Canvas>
  <Story name="case4">
    <Case4 comp={<span>😵‍💫</span>} />
  </Story>
</Canvas>

### Case 5 💀

export const Text = ({ text }) => <div>{text}</div>
export const Comp = ({ comp }) => comp
export const Case5 = (args) => <Comp {...args} />

<Canvas>
  <Story name="case5" args={{ comp: <Text text="👀" /> }}>
    {Case5.bind()}
  </Story>
</Canvas>
