Invalid characters IOBox string exception

[tgd]

While copy pasting text from a powerpoint and saving i got this exception.
Reopening the document was not possible (assume the same error on startup)

Probably related:

A patch can be destroyed when certain bytes are stored in the IOBox

I have another very similar document. broke2.vl (22.1 KB) I think it happened because I put some non-ascii symbols in the document. Not sure Judging from the screenshot, these symbols could be here. And I did not enter them directly, but displayed them in IOBOX from bytes. [image] the same situation in second file [image]

Fixed in upcoming. Strings containing invalid XML characters will get Base64 encoded. Thanks for reporting.
