This issue is caused by the ASCII to 8-bit Unicode Transformation Format (UTF-8) string conversion. If any of the following fields contain a non-standard US-English ASCII character it can cause unexpected behavior to occur:
To ensure that you do not run into the error, these fields cannot contain any non-standard US-English ASCII characters. Any characters other than ASCII 33 - 127, such as special French, Russian, or Japanese characters may produce one of the errors referenced in this article.
A future release of converter should correct this.

Ok, so this means that the issue is specifically within the virtual center (VC) environment. Sometimes it can be in the source physical machine specifically - but you are able to convert directly to ESX without error so I need you to check all of the VMs within VC and ensure that none of the annotation fields (the "notes" field) for each VM contain anything that is considered non-english.
Be careful not to overlook anything ... for example, you might have the comment in the annotation field such as:
USER: Frédéric, PASS: Côté
might show up as:
USER: Frdric, PASS: Ct
If this is the case, edit the "annotation" field and replace the non-english characters with english characters (change Frédéric to Frederic).
