If you've had trouble with broken Korean text in PuTTY, you can use this.
Yeoul SSH Client is a free SSH client that works with Korean out of the box. No need to tweak encoding settings. Just download and run.
It’s open source (MIT) and has no ads or in-app purchases.

■ What's different?
When you connect to a server via SSH, Korean characters often appear as □□□ or ¿¿¿. The server uses UTF-8, but the client reads it as EUC-KR, or vice versa.
Usually, you change the character set directly in the connection settings. If it differs per server, you must change it each time you connect. Input works, but pasting may break.
This client automatically detects whether it is UTF-8 or EUC-KR (CP949). No settings screen is required.
· Korean output does not garble
· Korean input (IME) supported
· Copy and paste work without breaking
· Automatically adapts to different character sets for each server
■ Other features
· SSH2 + Keep-alive (60 s) — auto-reconnect on disconnect (exponential back‑off)
· Multiple tabs — several servers in tabs
· Session save/load/copy/export, quick command buttons, session‑specific colors and icons.
· Dark/Light theme, adjustable font size
· Multilingual — Korean, English, Japanese, Chinese, German
· Security — AES-256-GCM credential encryption, no plaintext storage, OS keychain preferred (master password if unsupported)
· Telnet is also available.

■ Signature verification (important)
All files are code-signed with Yeoul Games' (yeoulgame) personal certificate. Please verify using the fingerprint below to ensure the file you received has not been tampered with.
Certificate SHA-256 fingerprint:
FA:D5:9C:51:12:E3:5A:84:6C:79:6C:28:C9:D7:7E:7C:7B:07:C4:CF:07:4D:13:38:AA:23:4E:E4:F0:2A:3B:DF
Format without delimiters:
FAD59C5112E35A846C796C28C9D77E7C7B07C4CF074D1338AA234EE4F02A3BDF
How to check
· Windows: Right‑click the file → Properties → “Digital Signatures” tab → select a signature and click “Details” → “View Certificate” → verify that the fingerprint matches the above value
· Linux/Mac: openssl x509 -in yeoulgame-public-cert.crt -noout -fingerprint -sha256
■ Things to know beforehand — a warning appears on first launch
Windows may display a 'Unknown Publisher' or 'Windows PC Protection' dialog. Don't be alarmed.
The program is signed. However, it is not signed with a paid certificate pre-approved by Microsoft, but with a certificate we created ourselves. Since this is a free tool, we did not purchase a certificate that costs money every year. That is why Windows says it does not know who the signer is.
Instead, we left the fingerprint above. If the fingerprint of the file you received matches the value above, it is the file signed by us and has not been altered in between.
· If a warning window appears → 「Additional Info」 → 「Run」
· The antivirus may flag it incorrectly. If so, add the folder to exceptions.
■ Installation
