Why do I get an error with this single line of code?
final pdfString = " (T) 20.5 (–H) 4 (E) ] % 5-element array of strings, reals, and intege"; print(utf8.decode(pdfString.codeUnits));
why I get
FormatException: Invalid UTF-8 byte (at offset 11)
I copied this string from O’Reilly book.
And independently of the context, how to recover the
pdfString if I have its byte representation only ?
As per the documentation for String.codeUnits:
An unmodifiable list of the UTF-16 code units of this string.
In effect, you are calling
utf8.decode() on a UTF-16 string, which is not going to work.
If you provide more context about what you’re actually trying to do, I may be able to offer a suggestion.
