XeTeX ⇒ ** WARNING ** Failed to convert input string to UTF16...

[bramp]

Hi,

I've recently switched from pdflatex to xelatex for compiling my thesis. Now when I switched my large document worked pretty much fine, and then I could start using the nice font features of xelatex.

However, one thing that keeps appearing in the log output of xelatex is:

** WARNING ** Failed to convert input string to UTF16...
** WARNING ** Failed to convert input string to UTF16...
** WARNING ** Failed to convert input string to UTF16...
** WARNING ** Failed to convert input string to UTF16...

There is no indication of where these lines are coming from, and it might be quite hard for me to create a simple test case as I have a huge document, and I wouldn't know where to begin.

So, has anyone seen this message before, and know what it means? Or does anyone know how I can make XeLaTeX give me more information. For example "Failed to convert input string on line 10".

thanks

Seem to be some problems with converting your input to the UTF16 encoding. What input encoding do you use (latin1, utf8, …)? I can't offer a solution, but you could take a look at the Example in the Wikipedia article for XeTeX [1]. The example uses the xunicode package, which may solve your problem.

I get the same warnings since I updated to Texlive 2008 (2007 didn't have this problem).
It seems to happen when the PDF bookmarks are written (hyperref is used).

Adding xunicode or fontspec don't help either.

Any ideas?
Thanks!

I have the same error message. It seems to happen when integrating the tables of content (maybe with the associated PDF bookmarks as you suggest) and it does not seem related to the actual text content or its encoding.

It would be much easier to give help if you provide a minimal working example (MWE) that reproduces the error. If you are using a True Type Font, make sure that you choose one that everybody has on his local machine.

Hello Thorsten,

Thanks for your message.

Actually, this problem does not seem severe or have much consequences.

Anyway, here is a MWE as you suggest. After some testing, it appears when making the table of contents and when the hyperref package is used with option unicode=true. Hint: the number of warnings is positively correlated to the number of sections in the document.

This may also be related to the following answered question:
