[BUG] Some Heisig primitives seem to be missing entirely

[calculuschild]

Describe the bug
Certain primitives / kanji reference primitives or radicals that never show up in the deck, and there is no link to them in the "Primitives" section of kanji that mention them in their "stories".

To Reproduce
Steps to reproduce the behavior:

1. Browse a "production" deck for the "door" primitive 戸
2. Notice the "stories" mention "ceiling... flag" as the primitives
3. "Flag" is a primitive that does not appear anywhere in the deck, and is not in the "primitives" section of the card. Instead, the "door" primitive itself shows as its own primitive.

Expected behavior
Primitives mentioned in cards should actually appear in the deck so they can be learned. Similar behavior for "Utilize" 用 and some others, but can't locate them at the moment.

Desktop (please complete the following information):

• OS and Version: Windows 11 and Andrioid 13
• Anki Version 2.1.65

Some of these missing primitives haven't been added because they consist of non-Unicode characters and previously couldn't be shown separately. See #175. I've made a solutions for this, available now for testing.
