Most username fields in 2026 still default to ASCII. A growing minority allow Unicode. Here's what to expect when you go beyond a-z.
Where Unicode is fine: display names. Almost every platform โ X, Discord, Instagram, TikTok โ lets your *display name* contain hangul, hiragana, kanji, accents, even emojis. Your *handle* is a separate field and is more restricted.
Where Unicode in the handle works: - Instagram allows non-Latin characters in handles in some regions, with caveats. - TikTok allows them in display names, not in @handles. - X and Reddit are ASCII-only in handles. - GitHub and Discord are ASCII-only.
The pragmatic rule: make your *handle* a clean ASCII version of what you want. Make your *display name* whatever you actually want to be called, including accents, hangul, or emoji.
Why: ASCII handles are easier to type when someone wants to mention you. If your handle is "๋ฐ์ง๋ฏผ" and someone on a US phone wants to tag you, they'll have to copy-paste from your profile. They probably won't. If your handle is "jimin.park" with a display name of "๋ฐ์ง๋ฏผ", they tag you in two seconds.
Emoji in handles: mostly blocked at the validation layer. Even when allowed, emoji handles look like spam to most users and don't render in older clients. Use emoji in display names, not in handles.
Romanization conventions: for Korean, use Revised Romanization (kim, park, lee โ not gim, bag, i). For Japanese, Hepburn (shibuya, ryou, jouji โ not syibuya, ryรด, zyรดzi). For Chinese, Pinyin without tone marks. These are what English-keyboard users will type if they're looking for you.
PickName generates ASCII handles only by design. Pair it with whatever Unicode display name you want.
