I would highly recommend storing this SVG information in an actual file, and then calling File.read!("path/to/file.svg"). Giant string literals like this are often a pain to deal with.

What is the tool that you use to write to the database ?

Because once you have your svg string in a variable, you should not have problems with special characters unless you are bulding raw sql like this: "INSERT INTO t VALUES('#{svg}');". This will not work.

But if you use a tool like Ecto, then your variable should fit into a text or binary column.

Hey @carter. Any time you have some sort of issue you’re running into, it helps if you can provide an example piece of data, as well as the code you tried to run, and the errors you ran into. It’s hard to help without this info.

Thank you for the reply. Here’s some examples of what I have tried and the error I get.

I second Ben’s recommendation to read from file.

Otherwise, you could try heredocs… (as long as string doesn’t contain and new line followed by whitespaces and """)

string = """
<?xml ..>
"""
