Internally we handle the content as Unicode and write it out by default as UTF-8. UTF-8 is similar to CP1252 on Windows but changes for quotes and some other characters.
We recommend using UTF-8 and telling the browser so it will handle it correctly on all platforms.
If you are using BuildVu, it will depend on if you are converting to HTML or SVG if we set it for you.
The charset is already set for you in the generated SVG files, this is in both the IDRViewer and content mode.
In the IDRViewer: The charset is already set for you.
In content mode: You will need to add <meta charset="utf-8" /> to the head tag of the page which has the converted content.
