I am having issues with pages on DAX Guide, e.g.: [https://dax.guide/now/ https://dax.guide/now/] These issues are when using Firefox on Windows 10. I have tried with Safe mode, and turning off Enhanced Tracking protection. I have made no changes to Javascript etc. '''Issue 1''' If I select a code example and try to run it in an external program (e.g. DAX Studio), it fails, and I have found that the reason is because the "space" characters are not ASCII code 32, which is a normal space, but instead ASCII 160. Another symptom of this is that you cannot unindent the paragraphs in a text editor (Vim), if you paste the code there. I have tested and this is not an issue with Chrome, Edge, or Opera. Also if I click on the "Try It" button, it takes you to a runnable version of the code where the spaces are correct. These are workarounds, but why is Firefox using the wrong space characters? '''Issue 2''' I have seen another response to this kind of question, but it did not exactly answer it: on the website as above, when you click on the "Copy" button, which points to https://dax.guide/now/#, the code is supposed to be copied to the clipboard, however it does nothing. This works without issue in the browsers mentioned above. I have noticed previously on other websites that URLs ending in hash / pound did not work in Firefox. Is this something that Firefox just does not handle, or is there a setting to enable it? Thanks
