When using the script typeform which goes from the text to the attribution, are attributions treated as paragraphs and therefore have the passage indicator or are they treated separately and have the word indicator.
Thanks for getting back so quickly. This looks like a brief note or an informal "letter" to someone. The UEB Literary committee consulted with the Braille Formats committee and agree that in this example, the addition of the script typeform applied to the entire text would not add anything for the braille reader and could be ignored. You can refer to Braille Formats §5.3 for the rule.
The Rules of Unified English Braille §9.9.1 does state that when a typeform passage extends over more than one text element, each element (e.g. paragraphs) is preceded by the typeform passage indicator and the terminator is placed where it ends. The paragraph and the attribution are different text elements. Braille Formats §9.4.1c tells us to retain typeforms that are needed for titles or some other text that requires distinction. That may not be the case in your example.
Sometimes, the rules are relaxed for special situations. If the purpose of using the typeform is to draw attention to the handwritten script being studied —as with any other distinct typeface, such as Old English or calligraphy —then in this case according to BF §5.1.2 you would retain the script passage. UEB says you would place a script passage indicator before each text element (the paragraph and the attribution), and the script terminator following the attribution as stated in UEB §9.9.1.
You are right about the difficulty in finding examples of script text. There are so many print typefaces that represent script (see attached example). In literature, it's usually seen in reference to a hand-written note, like your example.
