=== URIs with non-Latin1 characters were returning an error
// #TINY-13938

Previously, inserting images with data URIs that contained non-Latin 1 characters, such as SVG data URIs with a byte order mark (BOM), caused {productname} to throw an `InvalidCharacterError`. This occurred because {productname} used the `btoa` function to encode data URIs to base64, and `btoa` does not support characters outside the Latin 1 range. The error could cause the editor to hang or fail to process the image.

In {productname} {release-version}, data URIs are now encoded using `TextEncoder` before being passed to `btoa`, ensuring that non-Latin 1 characters are handled correctly. Images with data URIs containing such characters are now processed without errors.
