748851 - Web Developer Console incorrectly displays escaped hex/unicode characters

Status: RESOLVED FIXED

(DevTools :: Console, defect)

Description

[mrmr1993]

Displaying a string containing either "\\xNN" or "\\uNNNN", where \xNN or \uNNNN represent a printing character results in a backslash followed by the printing character, instead of the entered text.

For example, the input:
"\\x27 \\x22 \\x5c \\x6e \\x72 \\x74 \\x62 \\x66 \\x75 \\x78"

results in the output:
 "\' \" \\ \n \r \t \b \f \u \x"

And the input:
"\\x750075"

results in the output:
"u"

These are obviously incorrect; the input string should be displayed as is.

This appears to be caused by the process of escaping the string and then checking it for hex/unicode escaped characters. The second example appears to be a result of hex parsing before unicode parsing.
(ie. "\\x750075" => "\u0075" => "u")
