Convert files from ISO-8859-1 (Latin-1) to UTF-8, recursively

This requires recode to be installed (brew install recode or apt install recode).

The example shows HTML files only. Adjust as required.

Process:

1. (Recursively) find all files that end with *.htm or *.html.
2. For each match, check its file type using file.

Suppose you need to do a copy & paste of a conversation you had on Twitter to send it by email. Unfortunately, it's very hard to copy & paste it in toto from either the app or the web. Twitter makes it as hard as possible to do so, especially if you wish the whole conversation.

Conversations are conveniently stored as JSON files, but... you need to get access to them. One possible way to do so is the following:

1. Ask Twitter for a link to an archive of all your data to be downloaded (they'll take up to 24 hours to provide you with it)
2. Make sure jq is installed
3. "862741-8538292" represents a conversation between two Twitter IDs (recipientId)
4. You may have to massage the first line of direct-messages.js so that it reads
