A phone named "Gib's iPhone" with a typographic apostrophe was shown as
"Gib\342\200\231s iPhone".
busctl's default text output escapes every non-ASCII byte in octal, and
escapes it into the output rather than into a quoted string a
shell-style parser can undo, so shlex handed back the escape sequences
as literal characters and they went straight to the page. Apostrophes
were only the visible case: accents, emoji, quotes and backslashes were
all affected, and a name containing a quote could have split a field.
Property and method reads now use --json=short, which returns real
UTF-8, and the parsers read a document rather than splitting words.
That removes the class rather than unescaping octal by hand.
The fixtures were the reason this stayed invisible: every test fed the
text form and passed against output the helper is no longer asking for.
They now carry what busctl actually emits in the mode used, plus a case
for a non-ASCII name and one asserting the old text form is refused
rather than parsed wrongly.
