Typically these symbols are used very sparingly throughout a document, so I just grab them on a case-by-case basis as needed.

You could:

• Use the Character Map functionality in your OS.
  
  • You could also use a more powerful "Character Map" program, BabelMap:
    
    • http://www.babelstone.co.uk/Software/BabelMap.html
      
    • Note: This program is also very helpful when you need to find out which font on your computer has X character in it.
  • The "Insert Special Character" button in Sigil/Calibre can be used.
    
  • As Doitsu mentioned, if you use some symbols often, you could add them into Sigil as "Clips".
    
• In the code, you can type in the HTML Entities
  
  • © = ©
    
  • ® = ®
    
  • Here is a list of many HTML Entities: https://dev.w3.org/html5/html-author/charref
    
• Copy/Paste from elsewhere
  
  • I personally search on this site and copy/paste the characters.

  • As Toxaris mentioned, he recently put up a table of Unicode glyphs for the Symbol + Webdings + Wingdings 1/2/3 fonts:
    
    • http://toxaris.nl/glyphs/symbols.html
      
    • Note: He also implemented this into the next version of his Microsoft Word EPUB Tools Addon. If you created a document in Word using those fonts, his plugin will be able to automatically export those 5 fonts into their Unicode equivalents.

Indeed. While some of the very common ones like Copyright/Registered symbols SHOULD be on most devices, some of the obscure ones might not be.

We recently discussed Embedding Fonts for symbols in this topic:

https://www.mobileread.com/forums/sho...d.php?t=278187

These are very common and you should have no problems using them in your books:

Copyright: ©
Registered: ®

I probably wouldn't rely on these being in the device's fonts (although I haven't done any sort of extensive testing on this):

Circled Digits: ①②③④⑤⑥⑦⑧⑨⓪

These are probably much more rare:

Negative Circled Digits: ❶❷❸❹❺❻❼❽❾⓿

And these? I bet your bottom these wouldn't be on most devices:

Negative Circled Digits (11-20): ⓫⓬⓭⓮⓯⓰⓱⓲⓳⓴

The more obscure the symbols become, your best bet would probably be embedding a font specifically for these characters/glyphs/symbols (see topic above for example + Sample EPUBs).

As Toxaris mentioned, Symbola seems to be a great font for a lot of these obscure symbols.
