UnicodeIt

From Sven Kreiss

• This is a project by Kyle Cranmer and me.
• To use it: highlight some text and use the shortcut to replace latex with unicode characters
• Examples: p̅, x̲, ẋ, ∂̸, H → γγ, ℋ, ℒ, x ∈ ℝ, y ∈ ℂ, β, γ, ∑, →, ←, μ⁺, e⁻
• Tested with Mac OS X Lion and Snow Leopard 10.6.4 in Keynote, Safari, Mail, Pages, TextEdit; also tested on facebook.com, gmail.com, MediaWiki, TWiki using Safari

[edit] Installation on Mac OS Lion

• Download the workflow and open it
• Select File > Duplicate
• Save the duplicated workflow, e.g. as "UnicodeIt Copy"
• Setup keyboard shortcut under System Preferences > Keyboard > Keyboard Shortcuts > Services > Text > UnicodeIt Copy by clicking into the empty space behind it (e.g. Command+Option+Shift U)
• There is a delay first time you use the shortcut

All latex expressions and their unicode replacements: UnicodeItSymbols06.pdf

For programmers, here is the Python source code: unicodeIt06py.zip

[edit] Installation on Mac OS Snow Leopard

• Add the workflow to: /Users/<username>/Library/Services/UnicodeIt.workflow (create the Services folder if it is not there already)
• Setup keyboard shortcut under System Preferences > Keyboard > Keyboard Shortcuts > Services > Text > UnicodeIt by clicking into the empty space behind it (e.g. Command+Option+Shift U)
• There is a delay first time you use the shortcut

  • added combining marks: for example \bar{p} p̅, \underline{x} x̲, \dot{x} ẋ, \slash{\partial} ∂̸
• New in 0.4:
  • \rightarrow now has the alias \to
  • added mathbb and mathcal symbols including the symbols used for Hamiltonian and Lagrangian densities ℋ, ℒ and for real and complex numbers ℝ, ℂ (for all symbols see the UnicodeItSymbols.pdf file)

[edit] FAQ

• The native Mac applications work fine, but web browsers do not necessarily support the Mac's System Services:
  • Safari seems to be working fine.
  • Update: It works in version 8 of Chrome.
    For earlier versions of Google Chrome, UnicodeIt only works in the address bar (you can use that to quickly get a unicoded expression and copy&paste it into a website).
  • Firefox does not work with UnicodeIt: https://wiki.mozilla.org/Firefox/Feature_Brainstorming:Platform_Integration#Services_Integration_in_OS_X
