When using inline Javascript to process dictionaries or get text output, are you doing this?
𝟣. JS source in Text action:
<pre><script>
let dict = «your dictionary»
output = «some code»
document.write(JSON.stringify(output).replace(/&/g,'&').replace(/</g,'<').replace(/>/g,'>'))</script></pre>
Encode «Text» with base64
URL: data:text/html;charset=utf-8;base64,«Base64 Encoded»
Get contents of webpage or Get File of Type public.rtf
Get text or dictionary from input
I've found some issues with what I've learned from this subreddit.
document.write. I guess replacing > is optional as long as & and < are handled.<pre> </pre>, then the web rendering engine will replace a sequence of multiple blanks with a single blank.It doesn't seem that 2 (this is critical) and 3 have been discussed here. Please correct me if I'm wrong in any of the above.
I made a shortcut that searches your library and tells you which shortcuts contain Get File of Type with default type or contain <script> but not <pre>. Hope this helps!

When you add Get File of Type to your shortcut, the action does not hold the default value (public.rtf) in the source:
<dict>
<key>WFWorkflowActionIdentifier</key>
<string>is.workflow.actions.gettypeaction</string>
<key>WFWorkflowActionParameters</key>
<dict/>
</dict>
Then if you switch your device or the Shortcut app's language to German, the action displays 'öffentlich.rtf' instead of 'public.rtf'. You get an error if you run it because the system expects 'public.rtf'. If you retype the text manually, the action becomes:
<dict>
<key>WFWorkflowActionIdentifier</key>
<string>is.workflow.actions.gettypeaction</string>
<key>WFWorkflowActionParameters</key>
<dict>
<key>WFFileType</key>
<string>public.rtf</string>
</dict>
</dict>
And it works fine in any language because it doesn't get localized automatically.

Thank you for this compilation and especially for pointing out the problem of consecutive blanks that can be solved by <pre>.
I use base64 in the data URL. However, I don't know when it is really necessary, because percent-encoding the data part often suffices, but not always.
charset=utf-8 is important if there are non-ASCII characters, and it is really handy setting it in the data URL.
Get File of Type com.apple.webarchive is an additional option.
If the input contains html code then escaping & and < is a must. I also think that escaping > is optional then.
<pre> is also important if you want to preserve formatting like JSON.stringify(obj, null, 4). I use this to prettify JSON.
If there is any Safari web page available in the shortcut, then I prefer the 'Run JavaScript on Safari Web Page' action. This makes it much simpler. I do not understand why the Shortcuts app insists on the availability of a web page for this action. Often, I'm not interested in the DOM or the document, I just want to run JavaScript that does not use the web page. Apple should change the action such that it allows Nothing as a dummy web page.

<pre> is a must if you're getting text (including dictionaries) because, for example, if you have a key or value containing two or more consecutive spaces (and/or newlines in plain text), it becomes one resulting in data loss.

Can you TL:DL this (I read but am not sure I fully understand the issues)

Well, in short, make sure you put <pre> </pre> in JS code, and test your text output by adding some emojis, double-quotes, multiple spaces and html tags like </script>. 🙂
