Teks Kosong (Karakter)

Standard whitespace variants like No-Break Space and Em Space. Most platforms treat these as normal spacing and strip them from blank-field checks.

Characters like Zero-Width Space and Zero-Width Joiner take up no width but still count as real characters — the go-to pick for blank usernames.

Control text breaks rather than horizontal spacing. Rarely useful for blank-text tricks, but relevant for formatting multi-line bios or messages.

Control text direction for scripts that mix left-to-right and right-to-left languages. Using them elsewhere causes display glitches, not real invisibility.

Affect how adjacent characters render or break without adding visible space themselves, like Word Joiner and Combining Grapheme Joiner.

Modify how the preceding character displays, mainly for emoji styling. Included for completeness — not typically what you want for a blank name.

Hangul Filler and Hangul Choseong Filler are the most gaming-username-friendly options, often exempt from the whitespace-stripping rules that catch the rest.
