Configure the included Hotkey to allow you to search directly from other applications (select a character or Unicode escape and hit the Hotkey).

Use the special search queries search, prefs and help to navigate to the workflow's search, preferences and help file respectively. These work throughout the workflow.

Single-character queries are treated as exact matches for their own codepoint: if you enter p, you will only see the result for U+0070 LATIN SMALL LETTER P. To search for all P's, add a space after p (i.e. p ).

You can search for characters based on their names (e.g. LATIN CAPITAL LETTER U WITH DIAERESIS), aliases (e.g. EOL/LF/NL/NEW LINE for LINE FEED (LF)), hexadecimal (e.g. fe, 00fe, 0xfe) or decimal (e.g. 32), or HTML entity name (e.g. raquo, Uuml).

The workflow understands all formats it generates, so you can also enter a Go string escape (e.g. \U0001F37B) or Unicode ID (e.g. U+1F4A9). Configure the included Hotkey to be able to look up escapes directly from your editor.

You can restrict search to a particular field with the syntax <field>:<query>, e.g. entity:copy to find characters whose HTML entity name matches copy. The available fields are:

Note: All fields are treated as text, so hex:20 will return characters 0x20HH, not 0x20 (dec:32 will match 0x20, but also 32NN). Use 0x format to specify that a query is hexadecimal, i.e. 0x20. Append a space to dec:NN queries to only match that specific character (i.e. dec:32 ).

Finally, you can also use AND or OR in your queries, e.g. arrow AND left OR right (note AND and OR must be uppercase).

The workflow can be configured via several workflow environment variables. The most important ones can be set in the workflow by entering the query "prefs" in the Unicode search.

By default, the font size is calculated automatically based on the size of the image and the text. If the text is consistently too small or large with a particular font, you can increase/decrease RESIZE_FACTOR to increase/decrease the size of the text.

Alternatively, you can force a specific font size for all images by setting TEXT_SIZE.

You can assign your own modifiers to the search results to copy/paste quickly in your preferred format.

To assign a format to a modifier, add a new workflow environment variable with the name MOD_<KEY1>[_<KEY2>[_<KEY3>]] and set its value to the short name of the desired format.

For example, to override ⌘↩ to copy/paste JavaScript instead of the UTF-8 character, add a new variable named MOD_CMD with the value javascript. To re-assign UTF-8 character to ⌥⌘↩, add a new variable named MOD_CMD_OPT (or MOD_OPT_CMD … doesn't matter) with the value character.

Valid modifiers are CMD, OPT, SHIFT, CTRL.

You can copy (and paste) each character in some or all of the following formats:

TIP: You can get the short name for a format by using ⌘C on its item in the detail view.

• The Python/Go formatter outputs \u00AB-style escapes for characters up to 0xFFFF and \U000ABCDE-style escapes for higher ones.
• The JavaScript formatter outputs \xAB-style escapes for characters up to 0xFF, \uABCD-style escapes for characters up to 0xFFFF, and surrogate pairs for characters above that. Turn on ES6 Mode in the workflow settings to use ES6 \u{1ABCD}-style escapes instead of surrogate pairs.
