On-the-fly image manipulations issue with url encoding for special characters

[pyrobob83]

EE 7.2.11

I'm working on a legacy project, upgrading from EE2 > EE7, including adding on-the-fly image manipulations and I discovered that new or existing images that contain parentheses characters in the filenames generate on-the-fly resized images correctly, but the URLs to those resized images are converting the special characters incorrectly so the images are broken. The specific instance I discovered has an image named like filename_(8).jpg where the resized URL output gets changed to /_resize/filename_%25288%2529_resize_#hash#.jpg and it doesn't work. The encoded values for ( and ) are %28 and %29 so I don't know where those '25's are coming from. Manually updating the URL to /_resize/filename_(8)_resize_#hash#.jpg or even /_resize/filename_%288%29_resize_#hash#.jpg in the URL does load the resized image correctly.

I've not tested to see if this is an issue with other url-safe special characters.
