YNLC Legacy Fonts and Keyboard
Around 1994 YNLC sponsored development of a Macintosh font to produce materials in Yukon languages. The "Yukon Font", as it was called, had idiosyncratic character encoding and required special keyboard software to use. A PC version had slightly different character encoding which made it difficult to exchange documents between Mac and PC. With the change to Macintosh System X, the materials made with the old font were no longer as accessible as the keyboard no longer worked. YNLC made an OS X keyboard, code-named Painless, in order to be able to work with its legacy materials in the old font. The keystrokes are largely identical with those of the older method. Sometme later, after it appeared that there would be a long delay in Unicode being able to work with Yukon languages, YNLC developed fonts using open source outlines and the legacy character encoding. These are called "YNLC Legacy" (like Times), and "YNLC Legacy Sans" (like Arial or Helvetica). These replace the functionality of the Yukon and Yukon Sans fonts.
Until all major software works with the Unicode stacking diacritics, YNLC will be using these specialized fonts and keyboard for its language work on Macintosh. These fonts cover every character in every Yukon language and work in every Macintosh application. The fonts can be used on PC but there is no PC keyboard available. Characters on PC can be entered using, for example, the Insert Symbol function in MS Word.
The downloadable file, ynlclegacy.zip (150 KB) contains two TrueType fonts, YNLC Legacy, and YNLC Legacy Sans, as well as the Painless Keyboard. Keyboarding instructions are in painlesslayout.pdf (164 KB).
This package only works with System OS X 10.2 or higher. After downloading and unarchiving ynlclegacy.zip put the font files, YNLC Legacy and YNLC Legacy Sans, in /Library/Fonts, and put the keyboard files, Painless.keylayout and Painless.icns, in /Library/Keyboard Layouts. Log out and back in, or restart. Under System Preferences > International > Input Menu scroll down to see 
Painless and put a check beside it. Put a check beside "Show input menu in menu bar" at the bottom of the pane, and close. There will be a new keyboard icon in the menu bar, perhaps a US flag. Click on this icon to see and select keyboard menu choices.
To make a document, you need to select both font and keyboard before typing.
