Setting for Acrobat Professional: language of new Bookmark -?

I have Adobe Acrobat Pro 8.0, somewhat out of date at this point but it does what I need it to and I feel no urge to upgrade.

But it has one annoying proclivity. Whenever I create a new bookmark, in a PDF of my own creation, created on a Mac whose language settings are definitely American English, the bookmark appears in an Asian character set. Chinese, I think. When I right-click and select “Rename” and type over it, the replacement text is in regular Roman alphabet, so it’s just an inconvenience of the moment, but I assume it grabs the selected text to create the default Bookmark text, so if I could get it to appear in Roman alphabet characters to start with, that would save me a couple steps per each bookmark.

Anyone know where the hell it would be fetching the instruction to render the default bookmark like this?

It’s a Unicode bug of some kind. With the original text in your example, I could probably tell you exactly what they did wrong, but it’s some variant of “treat the incoming single-byte ASCII characters as a multi-byte Unicode string”.

It mostly comes through as Chinese because most characters across all languages are Chinese. They fill up a lot of the character space. But you can see some boxes with question marks in them as well, which are ones where it encoded to an invalid character. And there are some weird other symbols.

There’s probably nothing you can do, though there’s a chance there’s some buried setting for the character set encoding. You’ll have to look around.
