url can’t contain control characters.

That is correct. URLs (Uniform Resource Locators) are used to identify and locate resources on the internet. They consist of a series of characters that are used to represent the address of the resource, and these characters must conform to certain rules to be valid.

Control characters, such as tabs, line breaks, and carriage returns, are not allowed in URLs. These characters have special meanings in computer systems and could cause confusion or errors if included in a URL.

To ensure that a URL is valid and can be properly interpreted by web browsers and other software, it’s important to avoid including control characters in the URL. If you need to include special characters in a URL, you can use URL encoding to represent them in a safe and standardized way.

Ansible url can t contain control characters

It is generally not recommended to include control characters in URLs, as they can cause issues with parsing and interpretation of the URL by various software components, including web browsers and servers.

Control characters are special characters that do not have a visible representation, such as tabs, line breaks, and other non-printable characters. These characters are used for various purposes, such as formatting text or controlling the behavior of devices and software systems.

In the context of Ansible, which is an IT automation tool, URLs are often used to specify the location of remote resources, such as files or services, that need to be accessed or managed. It is important to ensure that these URLs are properly formatted and do not contain any invalid characters, including control characters, that could cause issues with the automation process.

To avoid issues with control characters in Ansible URLs, it is recommended to use URL encoding, which is a mechanism for representing special characters in a URL by replacing them with a sequence of characters that can be safely transmitted and interpreted. This can be achieved using the urlencode filter in Ansible, which converts special characters to their corresponding URL-encoded values.

For example, to encode a URL containing a space character, you can use the following Ansible playbook code:

- name: Example playbook hosts: localhost tasks: - name: Download file get_url: url: "" dest: "/tmp/myfile.txt"

In this example, the space character is replaced with the %20 URL-encoded value, which allows the URL to be properly parsed and interpreted by the remote server.


UnicodeEncodeError is an error that can occur when attempting to encode a Unicode string into a specific character encoding, such as ASCII or UTF-8. This error occurs when a character in the Unicode string cannot be represented in the specified encoding.

For example, let’s say you have a Unicode string containing a character from a language that is not supported by the ASCII character set, and you try to encode it using ASCII. In this case, you may receive a UnicodeEncodeError, indicating that the character cannot be encoded.

To resolve this error, you should ensure that the encoding you are using supports all of the characters in your Unicode string. UTF-8 is a widely used encoding that supports all Unicode characters, so using UTF-8 instead of ASCII can often resolve UnicodeEncodeErrors. You can also try to use a different encoding that supports the specific characters you need to encode.
