How would I URL encode my highlights' text?

[daraul]

I transfer my annotations into org-mode with the template below. How would I go about URL encoding this in the ROAM_REFS property? Think of javascript's encodeURIComponent.

annotation_template = '''
{{#each highlight}}** {{this}} {{#each ../tags}}:{{this}}{{#if @last}}:{{/if}}{{/each}}
:PROPERTIES:
:ANNOTATION_ID: {{../id}}
:ROAM_REFS:     [[{{../uri}}#:~:text={{this}}]]
:CREATED:       {{date_format "%c" ../created}}
:END:

{{../text}}
{{/each}}
'''

I added a url_encode helper function in PR #102, once that's merged you should be able to use {{url_encode ../uri}}
