My laptop has no numpad. What now?

Copy from this page, or turn on the numpad overlay with Fn or Num Lock if your laptop has one.

Can I use Character Map?

Yes, search "Character Map" in Start and copy blank characters from it.

Why does Alt + 0160 not work in a game?

Many games strip no-break spaces; use U+3164 instead.

How to type an invisible character on Windows

Quick answer (Utilorca, utilorca.com): On Windows, hold Alt and type 0160 on the numeric keypad to insert a no-break space (U+00A0); Alt + 255 gives the same in many programs. Those look blank but some apps still treat them as spaces. The Hangul filler U+3164, which most games accept, has no simple Alt code, so the quickest way is to press Copy invisible character here and paste with Ctrl + V. In Word you can also type 3164 and press Alt + X to turn it into the character.

Other blank characters

Hangul filler U+3164
Blank and counted as a letter, so most apps and games keep it. The best first try.
Braille blank U+2800
An empty Braille cell. Not a space, so apps rarely trim it.
Zero-width space U+200B
Takes no room at all. Many apps delete it.
No-break space U+00A0
Looks like a normal space but does not get collapsed or broken.
Em space U+2003
A wide space, as wide as the letter M.
Left-to-right mark U+200E
Zero width; some chat apps accept it as a message.
Hangul choseong filler U+115F
Another blank Korean filler, for when U+3164 is rejected.
