Description

Using the shorthand emoji names (":angry :") within a header forces the application to refuse exporting silently; however, copying and pasting Unicode-8 emojis from an online repository (🙃) into the heading, allows exporting, as expected.

• Can you reproduce the issue?

Steps to reproduce

**Note the &nbsp character, to not render such shorthand names in this bug report.

1. Create new Note
2. Insert: :angry :
3. Ctrl+[1-6]: To make the line a heading.
4. File > Export > HTML or PDF

Expected behavior:

Successful exporting to a file, with a prompt requesting save location, or at least an error.

Actual behavior:

Nothing. Menu closes silently.
