Bug fixes
TinyMCE 8.5.0 also includes the following bug fix<es>:
URIs with non-Latin1 characters were returning an error
Previously, inserting images with data URIs that contained non-Latin 1 characters, such as SVG data URIs with a byte order mark (BOM), caused TinyMCE to throw an InvalidCharacterError. This occurred because TinyMCE 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 TinyMCE 8.5.0, 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.
