Will not publish to pdf

Error reported by XML parser: An invalid XML character (Unicode: 0x1a) was found in the element content of the document.

Error using publish

.m file must contain valid XML 1.0 Standard characters.

Error in mdbpublish (line 54)

outputPath = publish(file, options);

Error using open (line 52)

File or variable name must be a character vector or string scalar.

My file name does not have any spaces and neither do any of the names of the path. I am unsure what is causing this.

Hi Kevin,

It is likely there is a special character somewhere in your file. If you are able to run the file without any issues, it is likely somewhere in the comments.

Attached is an example of an M file with a special character in its comments.

If you cannot find a special character in your file, another thing to check would be any places where "char" is called on a number. The way "char" function works is to create unicode commands of the numbers, so this is an easy way to generate invalid XML characters. For example:

char(20)

ans = ''

For converting numbers to characters it is recommended to use "num2str" instead of "char":

num2str(20)

ans = '20'
