Issue Summary

When using a custom field of type Text (multi-line or single line) and adding apostrophes enclosing a URL, one of the apostrophes is converted to Unicode.

This problem doesn't happen when using Wiki Renderer.

Other special characters e.g. "`^|&[]() - don't cause the problem.

Steps to Reproduce

1. Create a custom field of type "Text Field (multi-line)" or "Text Field (single line)".
2. Associate it with existing screens.
3. Create a new issue and update the content of the new custom field text: 'https://atlassian.com'

Expected Results

The issue shows the field exactly as:

 'https://atlassian.com'

Actual Results

You will see one of the apostrophes converted to Unicode:

 'https://atlassian.com'

Workaround

Switch the custom field render to Wiki Renderer.
