Module:Domino Unicode

This module is the helper module for Template:Domino Unicode to output Unicode characters of Domino tiles.

Note: This module only outputs the HEX codepoint. To convert it to the Unicode character in HTML, write &#x<some_codepoint>;.

• For example: to get the horizontal tile that has 1 followed by 2, write &#x{{#invoke:Domino Unicode|output|h|1|2}};, which gives you the output "🀺".

Usage

{{#invoke:Domino Unicode|output|<direction>|<num1>|<num2>}}

Parameters (letters are case-insensitive):

1. direction: to indicate whether the tile should be horizontal or vertical.
   • H or horizontal for horizontal tiles.
   • V or vertical for vertical tiles.
2. num1 (optional): the first number on the tile.
   • Valid numbers are: 0 – 6.
   • If omitted, then output the code point of the back of the tile.
     • {{#invoke:Domino Unicode|output|H}} or {{#invoke:Domino Unicode|output|horizontal}} gives "1F030".
     • {{#invoke:Domino Unicode|output|V}} or {{#invoke:Domino Unicode|output|vertical}} gives "1F062".
3. num2 (optional): the second number on the tile.
   • Valid numbers are: 0 – 6.
   • If omitted, then num2 is treated as the same as num1.
     • For example: {{#invoke:Domino Unicode|output|H|6}} gives the same output as {{#invoke:Domino Unicode|output|H|6|6}}: "1F061".
