💅 DESCRIPTION 💅

so every single one of these routines looks at a Unicode character and hands you back a boolean value. if it comes back non-zero, that means yes bestie, the character does belong to the character class that the routine you called is about 💖 (zero = it's giving "not in this class", iykyk).

and that's the whole thing fr fr — the rest of this page is just me telling you what each character class actually is. no cap. 🌈

👑 CHARACTER CLASSES 👑

okay so this is the main character section, let's go one by one 🫶

• Tcl_UniCharIsAlnum — tests if the character is an alphanumeric Unicode character. letters AND numbers, obsessed ✨
• Tcl_UniCharIsAlpha — tests if the character is an alphabetic Unicode character. just letters, iconic 💜
• Tcl_UniCharIsControl — tests if the character is a Unicode control character. the sneaky invisible ones 😭
• Tcl_UniCharIsDigit — tests if the character is a numeric Unicode character. numbers slay 🔥
• Tcl_UniCharIsGraph — tests if the character is any Unicode print character except space. so like, printable but no spaces allowed, she's picky 💅
• Tcl_UniCharIsLower — tests if the character is a lowercase Unicode character. soft launch energy 🦋
• Tcl_UniCharIsPrint — tests if the character is a Unicode print character. printable, full stop 🎀
• Tcl_UniCharIsPunct — tests if the character is a Unicode punctuation character. commas and friends ate, honestly ⭐
• Tcl_UniCharIsSpace — tests if the character is a whitespace Unicode character. the quiet ones 🌸
• Tcl_UniCharIsUpper — tests if the character is an uppercase Unicode character. LOUD. main character energy 👑
• Tcl_UniCharIsWordChar — tests if the character is alphanumeric or a connector punctuation mark. that's the word-char combo meal 🍓

reminder bestie: every one of these returns a boolean, and non-zero means "yep, it's in the class". don't overthink it 💖
