Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.

The Korean Character Counter (글자수 세기) analyzes Korean Hangul text for job applications, university essays, and resumes (자기소개서). It calculates character counts with and without spaces, Hangul syllables, Jamo, and accurate byte lengths in both modern UTF-8 and legacy Korean enterprise EUC-KR encodings.
\text{Bytes}_{\text{EUC-KR}} = 2 \times N_{\text{Hangul}} + 1 \times N_{\text{ASCII}}, \quad \text{Bytes}_{\text{UTF-8}} = 3 \times N_{\text{Hangul}} + 1 \times N_{\text{ASCII}}Korean enterprise recruitment portals (e.g., Saramin, JobKorea) frequently enforce character or EUC-KR byte limits for application essays.
Scenario: Analyzing the phrase "안녕하세요 반갑습니다" (Hello, nice to meet you)
Total characters with spaces: 11 characters.
Characters without spaces: 10 Hangul characters.
EUC-KR bytes: 10 × 2 bytes + 1 space = 21 bytes.
UTF-8 bytes: 10 × 3 bytes + 1 space = 31 bytes.
공백 포함 (with spaces) counts every character, space, and line break. 공백 제외 (without spaces) counts only actual Korean syllables, numbers, and punctuation.
Many legacy HR database systems use 2-byte EUC-KR encoding where Korean characters take 2 bytes and English/spaces take 1 byte. A 1,000-byte limit equals approximately 500 Korean characters.
Most Korean enterprises (e.g., Samsung, Hyundai, CJ) specify question prompts between 500자, 800자, 1,000자, or 1,500자 (usually measured with spaces).
Completed Hangul syllable blocks (e.g., 가, 나, 다) count as 1 character and 2 bytes in EUC-KR. Incomplete consonants or vowels (ㄱ, ㄴ, ㅏ) are tracked separately as Jamo.
