🫶 ARGUMENTS 🫶

• int ch (in) — the Unicode character you want examined. that's the whole assignment, she's the main character 🌸

---

💅 DESCRIPTION 💅

so like, all of these routines look at Unicode characters and hand you back a boolean value, periodt. a non-zero return value means the character does belong to the character class that the routine you called is responsible for. that's it, that's the vibe 💖

the rest of this doc is just me telling you which character class goes with which routine. no skips, no shortcuts, we're doing all of them 😭

🌈 CHARACTER CLASSES 🌈

• Tcl_UniCharIsAlnum — tests if the character is an alphanumeric Unicode character. iconic behaviour ✨
• Tcl_UniCharIsAlpha — tests if the character is an alphabetic Unicode character. yes queen, letters only 💜
• 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, she ate 🔥
• Tcl_UniCharIsGraph — tests if the character is any Unicode print character except space. almost print, but no space allowed, sorry 🎀
• 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, presentable, glowing ⭐
• Tcl_UniCharIsPunct — tests if the character is a Unicode punctuation character. the commas and exclamation points carrying the whole sentence 💅
• Tcl_UniCharIsSpace — tests if the character is a whitespace Unicode character. taking up space, literally 🌸
• Tcl_UniCharIsUpper — tests if the character is an uppercase Unicode character. ALL CAPS MOMENT 👑
• Tcl_UniCharIsWordChar — tests if the character is alphanumeric or a connector punctuation mark. the word-char girlie, she's versatile 🧚
