Frequently Asked Questions

EUC-KR (Extended Unix Code for Korean) is a variable-width character encoding for Korean text. It uses 1 byte for ASCII characters and 2 bytes for Korean Hangul syllables, based on the KS X 1001 standard. Widely used in South Korea from 1990s to early 2010s.

EUC-KR remains common in Korean government systems, banking infrastructure, legacy corporate databases, and older websites. Many Korean government portals, financial institutions, and university systems still output EUC-KR encoded data for backward compatibility.

CP949 (Code Page 949, also called UHC or Unified Hangul Code) is Microsoft's extension of EUC-KR. It adds 8,822 additional Hangul syllables beyond KS X 1001. Many Korean Windows systems label files as EUC-KR when they're actually CP949. Our converter supports both.

UTF-8 is the universal web standard supporting all languages in one encoding. Converting EUC-KR to UTF-8 enables proper display on modern systems, prevents mojibake (garbled text), allows database migration, and ensures international compatibility for Korean content.

Mojibake (garbled characters) occurs when EUC-KR text is incorrectly interpreted as another encoding like UTF-8 or Windows-1252. Korean characters appear as random symbols. This happens when servers send wrong charset headers or files lack encoding declarations.

The tool uses TextDecoder API with 'euc-kr' encoding to properly decode the 2-byte Korean syllable blocks (0xA1-0xFE range). It correctly maps KS X 1001 code points to Unicode Hangul, preserving all 2,350 common syllables plus Hanja (Chinese characters used in Korean).

Both. You can paste text directly or upload files (TXT, CSV, HTML, SQL dumps). The tool reads raw bytes and decodes them as EUC-KR, then re-encodes to UTF-8. Perfect for converting database exports or legacy Korean website content.

If Korean text displays as gibberish (like 㚸뱛), it's likely EUC-KR misread as UTF-8. If you see question marks or boxes (□), UTF-8 was misread. Real EUC-KR files from Korean systems will show clean Hangul when decoded properly.

Issues include: (1) CP949 vs pure EUC-KR confusion—try both if characters are missing; (2) Mixed encodings in one file from copy-paste; (3) Incorrect BOM markers; (4) HTML entities mixed with encoded bytes. Our tool handles these edge cases.

This tool processes one file at a time for accuracy. For batch conversion, process files individually or use command-line tools like iconv. All processing happens locally in your browser for privacy.
