str.strip('"') in visitStringValue() and visitPair() removes every '"'
on either side of the token, not just the outer delimiters, so a value
ending in an escaped quote (e.g. '"foo \"bar\""') loses its trailing
backslash-escaped '"' character. The Agtype grammar guarantees STRING
tokens always carry exactly one delimiter on each side, so slice with
[1:-1] to strip them precisely.
Fixes apache#2418

Fixes #2418.
ResultVisitor.visitStringValue()andvisitPair()indrivers/python/age/builder.pyusestr.strip('"')to remove the surrounding delimiters from agtype STRING tokens.str.strip()removes all matching characters from both ends, so when a property value or object key starts or ends with an escaped quote the parser drops the data character along with the delimiter:"foo \"bar\""foo \"bar\"foo \"bar\"\"leading"\"leadingleading"trailing\""trailing\"trailing\The Agtype grammar (
