vape

ｆｕｌｌ ｗｉｄｔｈ ａｅｓｔｈｅｔｉｃｓ

vape is a command-line tool that converts text into "vaporwave" text - fullwidth UTF-8 characters.

More technically, characters in the range U+0021 to U+007E are translated forward by 0xFEE0, and the space character U+0020 is converted to the ideographic (fullwidth) space U+3000.

Usage

$ printf 'the longer you live, the more ad revenue you generate\n' | vape
ｔｈｅ　ｌｏｎｇｅｒ　ｙｏｕ　ｌｉｖｅ，　ｔｈｅ　ｍｏｒｅ　ａｄ　ｒｅｖｅｎｕｅ　ｙｏｕ　ｇｅｎｅｒａｔｅ

You can also append up to 255 random fullwidth katakana:

$ printf 'born to die\n' | vape -k 5
ｂｏｒｎ　ｔｏ　ｄｉｅ　リマヾソル

ａｃｈｉｅｖｅ　ａｅｓｔｈｅｔｉｃｓ　ａｔ　ｈｇｉｈ　ｓｐｅｅｄ
