In unicode-full.yaml, replace individual chars with ranges

[NSoiffer]

Many unicode-full.yaml files have thousands of lines like:

 - "𝔸": [t: "𝔹CL⠁"]             # 0x1d538 
 - "𝔹": [t: "𝔹CL⠃"]             # 0x1d539 
 - "ℂ": [t: "𝔹CL⠉"]             # 0x2102 
 - "𝔻": [t: "𝔹CL⠙"]             # 0x1d53b 
 - "𝔼": [t: "𝔹CL⠑"]             # 0x1d53c 

These should be replaced with ranges such as:

 - "𝔸-𝕐":    # 0x1d504 - 0x1d51d ('z' version is reserved)
    - tc: "DC"
    - spell: "translate('.', '𝔸𝔹𝔺𝔻𝔼𝔽𝔾𝔿𝕀𝕁𝕂𝕃𝕄𝕅𝕆𝕇𝕈𝕉𝕊𝕋𝕌𝕍𝕎𝕏𝕐', 'abcdefghijklmnopqrstuvwxyz')"

This saves a lot of file space and is a little faster to load. You need to be careful about characters such as "ℂ": # 0x2102 which is not in the math alphanumerics. See Braille/UEB/unicode-full.yaml for a file that has been updated.

This is probably a good issue to use AI on.
