Frequently Asked Questions
What is an invisible character?
A Unicode code point that renders with no visible glyph (U+200B zero width space, U+3164 Hangul filler). Some systems still allocate tiny space or render a placeholder.
How do I create an empty username?
Most platforms reject spaces but accept U+3164 Hangul Filler. Pick it, generate one or two copies, paste into the username field. Many apps now detect and block this.
Are they safe?
