To create an UTF-8 file using vi(1) and open it correctly as UTF-8 file in TextEdit (as opposed to Open As… UTF-8):

1. vi file
2. xattr -w com.apple.TextEncoding 'UTF-8;134217984' file
3. open file

HP scanjet 4670

Nice vertical flatbed scanner but shitty crappy software. Come on HP, you can do better! After upgrade to Mac OS X 10.5.8 scanner did not work anymore.

• First, follow instructions on hp scanjet 4670 and OS X 10.4.8 -- YIKES! » I Did Get It Going....
• Next, follow instructions on Scanjet 4670 driver for Mac OS Leopard 10.5? » Kenneth Koller's comment.
  1. Download COL10842b.dmg
  2. Double-click COL10842b.dmg to mount.
  3. Once the window opens with the installers...control click it...and select see package contents.
  4. Navigate to contents/macos/subinstallers.
  5. Double-click on the hp scanjet 4600.
  6. Go to top directory of SJ4600 (mount point *.dmg) and double-click HP ScanJet Software Installer to install all components (not sure if this is still necessary).
  7. Enjoy

I will never buy any HP products anymore.
