Describe the bug

just created my account to post the issue.

I found that translated texts contain invisible special characters. These characters appear at the positions where variables or references exist.

<template>
  <span>{{ $t('bar', { baz: 'baz' }) }}</span>
</template>

<fluent locale="ja">
foo = foo
bar = foo{foo}bar{$baz}baz
</fluent>

<script setup lang="ts"></script>

copy "foo⁨foo⁩bar⁨baz⁩baz" and you can see it is actually "foo<U+2068>foo<U+2069>bar<U+2068>baz<U+2069>baz" by pasting on somewhere shows unicode special characters

thanks in advance and thank you for this great project! this saved my life when I was overwhelmed by vue-i18n

Reproduction

1. https://stackblitz.com/edit/fluent-vue-examples-pt5ujbab?file=src%2FApp.vue
2. copy "Hello, World" under the "$t method"
3. paste it on WebStorm or something that shows special characters
4. see symbols of First Strong Isolate(U+2068) and Pop Directional Isolate(U+2069)
