Javascript将文本转换为粗体unicode字符集

Question

I would to convert text to unicode bold format.

I found

• [U+1D5D4 - U+1D5ED] as BOLD CAPITAL [A - Z]
• [U+1D5EE - U+1D607] as BOLD CAPITAL [a - z]

How can I convert text to BOLD CAPITAL with unicode?

Thanks

Here is a quick code snippet which does what you are asking for:

 let text = "This is a text: ABC"; function translate (char) { let diff; if (/[AZ]/.test (char)) { diff = "𝗔".codePointAt (0) - "A".codePointAt (0); } else { diff = "𝗮".codePointAt (0) - "a".codePointAt (0); } return String.fromCodePoint (char.codePointAt (0) + diff); } let newText = text.replace (/[A-Za-z]/g, translate); console.log (text); console.log (newText); // -> "𝗧𝗵𝗶𝘀 𝗶𝘀 𝗮 𝘁𝗲𝘅𝘁: 𝗔𝗕𝗖"

A regex-free answer inspired by @Albert Stein solution:

 const upperDiff = "𝗔".codePointAt(0) - "A".codePointAt(0); const lowerDiff = "𝗮".codePointAt(0) - "a".codePointAt(0); const isUpper = (n) => n >= 65 && n < 91; const isLower = (n) => n >= 97 && n < 123; const bolderize = (char) => { const n = char.charCodeAt(0); if (isUpper(n)) return String.fromCodePoint(n + upperDiff); if (isLower(n)) return String.fromCodePoint(n + lowerDiff); return char; }; const bolderizeWord = (word) => [...word].map(bolderize).join(""); console.log("a" + bolderize("a")) console.log(bolderizeWord("Bold") + " move")
