Customizing Plone 5.1.6: Bundle Builder hangs forever

Plone Support Customizing Plone

I noticed issues with 'unicode' characters in the files.

In other words:
If the files contained for example

.someclass:after { content: 'å' }

the building / saving would not work.

But if you change to

.someclass:after { content: 'å' }

it was possible to save ( maybe build, too )

Could you try

  1. Make a simple less file
  2. Bulid it
  3. Make a less file with some unicode letters in it
  4. Build it.

Does both fail ?
