Added Unicode characters to lettering guidelines

Guidelines:

• Coins https://en.numista.com/help/lettering-obverse-reverse-and-edge-125.html
• Banknotes https://en.numista.com/help/lettering-obverse-and-reverse-169.html

These guidelines have different Unicode characters for add circles, crosses, stars, and other small drawings to the lettering field of pages of object.

There are coins with 8-pointed stars (for example, many of
https://en.numista.com/catalogue/index.php?e=espagne&r=&st=147-150-149&cat=y&ru=159&ca=3&o=v) and this character was not included in guidelines.

The pages of the example use the character

🟎 (thin 8-pointed star, with the point at 0 o'clock)

and I found three more that might be useful

🟐 (thick 8-pointed star, with the point at 0 o'clock)
✷ (thin 8-pointed star, with the point at 0.75 o'clock)
✸ (regular 8-pointed star, with the point at 0.75 o'clock)

I added these characters to the guidelines. Correct?
 

🟎 🟐 ✷ ✸

Do you know if there are also Unicode characters for the 7-pointed star? There are also coins with them.

There is no heptagram or 7-poinzed star in the Unicode register.

It can be useful to have the possibility to insert small SVG or PNG files  in these cases?

I needed the hexagon symbol in the lettering of an item of exonumia. Searching for this, I found ⬡ ⬢ ⬣. 

I think they could be useful in more cases, so I added them to the help articles.

I needed a 4-pointed star. I added these to the help articles: ✧ ✦

I needed a 5-pointed star with an inner star. I added: ☆

I needed a 4-petals flower, and added to FAQs: ꕤ ꕥ

I also grouped similar symbols.

There are several additions you made that I cannot see on my end (Android / Chrome 143)

There is a problem with the fonts installed in your system. See: https://en.numista.com/forum/topic165093.html

Android 12 can display 6th symbol (U+1F542 CROSS POMMEE) in coin punctuation examples. It can't handle other six characters.

Android 15 can't display 6th symbol and other six in Compendium's screenshot.

Google removed some fonts from the build.

Symbola font supports U+1F542.

Yes I have Android 16
