When I read the documentation about set-fontset-font, I found there is a sentence like below:
(set-fontset-font NAME TARGET FONT-SPEC &optional FRAME ADD)
Modify fontset NAME to use FONT-SPEC for TARGET characters.
...
TARGET may be a script name symbol. In that case, use FONT-SPEC for all characters that belong to the script.
TARGET may be a charset. In that case, use FONT-SPEC for all characters in the charset.
...
But I cannot find any more information about what the "script name symbol" is?
I search via google to find some example that uses 'kan 'ascii 'kana. But I don't find any detail information about what it exactly is? Is there a way to list all the possible value?
BTW,
Is there a way to list all the possible value of "charset" that is available to set-fontset-font?

where FONT is a string naming the font you want, for example, "Droid Sans Mono-10". This should work on all platforms. As of Emacs 23, all of your system fonts including TrueType are available to Emacs.
GlobalTextScaleMode – Adjust font size for all buffers at once using face remapping (Emacs 23+). You can use any of the following to increase or decrease the font size for the current frame, effectively resizing it incrementally – zooming the text in or out. ‘zoom-in/out’, ‘zoom-in’, ‘zoom-out’ (in zoom-frm.el) – see above for the descriptions.
Modifying ‘ fontset-default ’ will also affect other fontsets that use it as a fallback, so can be an effective way of fixing problems with the fonts that Emacs chooses for a particular script.
If you are running Linux, you may be able to run `xfontsel` from a shell. This program helps you select a font. Once you’ve found one that you like, save the specification string. In my version, clicking the “select” button near the top left copies the string to my clipboard so I can yank (paste) it into Emacs.
A "script name symbol" is a means to associate a lisp symbol with a particular charset, a set of charsets, or a range of characters. So, for example, if you look at the value of the variable "charset-script-alist", you will see an Alist of charsets vs the corresponding most appropriate script name symbols. If you look at the value of the variable "script-representative-chars", you will see an Alist of script name symbols vs the representative characters. The variable "char-script-table" shows the full mapping of characters to script name symbols (as specified by "script-representative-chars"). I don't know of any "definitive" list of script names (for example, "ascii" is a script name as well but isn't contained in these 2 variables); however, the values that are contained in the variables "charset-script-alist" and "char-script-table" are probably most of them.
To get a list of all the possible values of "charset" that is available to set-fontset-font, use the "list-character-sets" function. You can also use the "list-charset-chars" function to see the list of characters contained in a specific charset.
