Type
objects created in Illustrator 10 and earlier are uneditable until
you update them for use in later versions. After you update you
have access to all the text features in Illustrator CS3, such as
paragraph and character styles, optical kerning, and full OpenType® font support.
You don’t have to update the text if you don’t need to edit it.
Text that has not been updated is called legacy text.
You can view, move, and print legacy text, but you can’t edit it.
Legacy text has an x through its bounding box when selected.
After updating legacy text, you may
notice some minor reflow changes. You can easily readjust the text
on your own, or you can use a copy of the original text for reference.
By default, Illustrator appends the word “[Converted]” to the filename whether
or not you update the text in a file, effectively making a copy
of your document to preserve the integrity of your original file.
You can then choose to update the original later or, if you already
updated it, go back to the original version.
Note: If you don’t want
Illustrator to append the filename, choose Edit > Preferences >
General (Windows) or Illustrator > Preferences >
General (Mac OS), and deselect Append [Converted] Upon
Opening Legacy Files.
