unicopy | Convert the Codepoints

CLI utility which converts Unicode codepoints to a string (or vice versa). Copies the result to the system clipboard or just prints it to the console.

Can also convert codepoints to many dump formats.

Setup

Make sure you have Ruby installed and installing gems works properly. Then do:

$ gem install unicopy

Usage

Codepoints to String

Codepoints format is hexadecimal, "U+" is permitted, examples:

$ unicopy 52 75 62 79 --print
Ruby

$ unicopy U+0052 U+0075 U+0062 U+0079 --print
Ruby

String to Codepoints

$ unicopy --string Ruby --print
U+0052 U+0075 U+0062 U+0079

Options

--help                |    | this help page
--parse-decimal       |    | interpret given codepoints as decimal, instead of hexadecimal values
--print               | -p | do not copy to system clipboard, but print to screen
