待解决的问题：
笔记emoji 字形需要避开数字和字母：
先看看思源的 emoji 用到的 Unicode 有哪些： 计算方法// 把整个 json 赋值给变量 jsonData
let jsonData = [
{
"id": "people",
"title": "Smileys & People",
"title_ja_jp": "スマイリーと人",
"title_zh_cn": "笑脸和人类",
"items": [
{
"unicode": "1f600"
},
{
"unicode": "1f603"
}
]
},
{
"id": "nature",
"title": "Animals & Nature",
"title_ja_jp": "動物と自然",
"title_zh_cn": "动物和自然",
"items": [
{
"unicode": "1f435"
},
{
"unicode": "1f412"
},
{
"unicode": "1f3f3-fe0f-200d-1f308"
},
{
"unicode": "1f3f3-fe0f-200d-26a7-fe0f"
}
]
}
];
// 提取unicode并转换为十六进制数字，同时去重
let unicodeList = Array.from(new Set(jsonData.flatMap(category =>
category.items.flatMap(item => item.unicode.split('-').map(part => parseInt(part, 16)))
)));
// 排序
unicodeList.sort((a, b) => a - b);
// 计算范围
let ranges = [];
for (let i = 0; i < unicodeList.length; i++) {
let start = unicodeList[i];
while (i < unicodeList.length - 1 && unicodeList[i + 1] === unicodeList[i] + 1) {
i++;
}
let end = unicodeList[i];
if (start === end) {
ranges.push(`U+${start.toString(16).toUpperCase()}`);
} else {
ranges.push(`U+${start.toString(16).toUpperCase()}-${end.toString(16).toUpperCase()}`);
}
}
// 输出结果
console.log(ranges.join(', '));其中 U+30-39 是数字 0-9，但因为被用在“按键” emoji，所以不能通过修改 emoji 字体的 unicode-range 范围来剔除数字字形。 “按键” emoji 之一但可以反过来从非 emoji 字体下手，用正常的数字字形去覆盖 emoji 的数字字形（外加空格和全角空格）： :root {
--b3-font-family: "DejaVu Sans Number", "Noto Color Emoji", "DejaVu Sans";
}
@font-face {
font-family: "DejaVu Sans Number";
src: local("DejaVu Sans");
unicode-range: U+20, U+30-39, U+3000;
}不过由于 emoji 字体里还有大量其他字符的字形，所以直接排在前面可能还是会有问题，所以保险一点改为放在后面，前面放跟思源的 emoji 范围相同的范围来覆盖： :root {
--b3-font-family: "Partial Fonts", "Partial Emoji", "DejaVu Sans", "Noto Color Emoji";
}
@font-face {
font-family: "Partial Fonts";
src: local("DejaVu Sans");
unicode-range: U+30-39;
}
@font-face {
font-family: "Partial Emoji";
src: local("Noto Color Emoji");
unicode-range: U+23, U+2A, U+30-39, U+A9, U+AE, U+200D, U+203C, U+2049, U+20E3, U+2122, U+2139, U+2194-2199, U+21A9-21AA, U+231A-231B, U+2328, U+23CF, U+23E9-23F3, U+23F8-23FA, U+24C2, U+25AA-25AB, U+25B6, U+25C0, U+25FB-25FE, U+2600-2604, U+260E, U+2611, U+2614-2615, U+2618, U+261D, U+2620, U+2622-2623, U+2626, U+262A, U+262E-262F, U+2638-263A, U+2640, U+2642, U+2648-2653, U+265F-2660, U+2663, U+2665-2666, U+2668, U+267B, U+267E-267F, U+2692-2697, U+2699, U+269B-269C, U+26A0-26A1, U+26A7, U+26AA-26AB, U+26B0-26B1, U+26BD-26BE, U+26C4-26C5, U+26C8, U+26CE-26CF, U+26D1, U+26D3-26D4, U+26E9-26EA, U+26F0-26F5, U+26F7-26FA, U+26FD, U+2702, U+2705, U+2708-270D, U+270F, U+2712, U+2714, U+2716, U+271D, U+2721, U+2728, U+2733-2734, U+2744, U+2747, U+274C, U+274E, U+2753-2755, U+2757, U+2763-2764, U+2795-2797, U+27A1, U+27B0, U+27BF, U+2934-2935, U+2B05-2B07, U+2B1B-2B1C, U+2B50, U+2B55, U+3030, U+303D, U+3297, U+3299, U+E50A, U+FE0F, U+1F004, U+1F0CF, U+1F170-1F171, U+1F17E-1F17F, U+1F18E, U+1F191-1F19A, U+1F1E6-1F1FF, U+1F201-1F202, U+1F21A, U+1F22F, U+1F232-1F23A, U+1F250-1F251, U+1F300-1F321, U+1F324-1F393, U+1F396-1F397, U+1F399-1F39B, U+1F39E-1F3F0, U+1F3F3-1F3F5, U+1F3F7-1F4FD, U+1F4FF-1F53D, U+1F549-1F54E, U+1F550-1F567, U+1F56F-1F570, U+1F573-1F57A, U+1F587, U+1F58A-1F58D, U+1F590, U+1F595-1F596, U+1F5A4-1F5A5, U+1F5A8, U+1F5B1-1F5B2, U+1F5BC, U+1F5C2-1F5C4, U+1F5D1-1F5D3, U+1F5DC-1F5DE, U+1F5E1, U+1F5E3, U+1F5E8, U+1F5EF, U+1F5F3, U+1F5FA-1F64F, U+1F680-1F6C5, U+1F6CB-1F6D2, U+1F6D5-1F6D7, U+1F6DC-1F6E5, U+1F6E9, U+1F6EB-1F6EC, U+1F6F0, U+1F6F3-1F6FC, U+1F7E0-1F7EB, U+1F7F0, U+1F90C-1F93A, U+1F93C-1F945, U+1F947-1F9FF, U+1FA70-1FA7C, U+1FA80-1FA89, U+1FA8F-1FAC6, U+1FACE-1FADC, U+1FADF-1FAE9, U+1FAF0-1FAF8, U+E0062-E0063, U+E0065, U+E0067, U+E006C, U+E006E, U+E0073-E0074, U+E0077, U+E007F;
}去除 Segoe UI Emoji 和 Segoe UI Symbol 里滥竽充数的 emoji 之后还用到的 Unicode 有： 所以最终能尽可能完整显示 emoji 的方法是： @font-face {

local("Luxi Sans"),
local("DejaVu Sans"),
local("Hiragino Sans GB"),
local("Segoe UI"),
local("Microsoft Yahei"),
