[4.x]: Plain Text Field strips out em dash character on save.

[myleshyson]

What happened?

Description

Noticed today that the plain text field strips out the em dash character on save because when it serializes the value it passes the value through LitEmoji::unicodeToShortcode. This is a problem because we're using a text field with a drop down to construct a title for a particular entry type, and the text field should allow em dashes (and probably other utf-8 charachters) like the native title field. Em dashes are persisted when used in the native title field.

Steps to reproduce

1. Create a plain text field.
2. Put some text in it with an em dash character.
3. Save the entry and see that the em dash character is removed.

Expected behavior

Em dashes (and probably other unicode characters) should not be filtered out when saving a plain text field.

Actual behavior

Em dashes are filtered out when saving a plain text field.

Thanks for reporting. Various other punctuation characters are also affected by this. There’s also an open issue for this in elvanto/litemoji GitHub (link). We’ll discuss options internally, and once I have more info, I’ll update this issue again.
