Issue with RTL formatted language mixed with Latin words

[happpyface]

There is a problem that I'm not sure it is related to Grammy or not.
When using RTL language text (like Persian) that has LTR words within the Latin word get reversed. example

# fa.ftl
start = سلام { $name }! چطور می‌تونم کمکت کنم؟ 

The above sentence in English is "Hello { $name}! how can i help you?"

if name is Parsa (which is loaded from ctx.from.first_name) the result must be like below:
سلام Parsa! چطور می‌تونم کمکت کنم؟
but the the result will be like this:
سلام asraP! چطور می‌تونم کمکت کنم؟

I tried the Fluent playground to check if it's related to Fluent but it's not! check the link below:

Is its result really that or is it just your client rendering it that way?

Maybe this will help.
the second reply is displayed correctly in telegram.

bot.command('test', async ctx => {
  await ctx.reply(ctx.t('start', { name: 'Parsa' }))
  await ctx.reply('سلام Parsa! چطور می‌تونم کمکت کنم؟')
})

Do you have useIsolating set to false in the i18n/fluent configuration? It is recommended to be enabled for RTL languages. That should be why you're having this issue.
