Thanks for the suggestion @mhseiden .
I tried escaping by `escapeJava` and it may fix this issue but I noticed it
escapes all of "\", means the number of "\" will be doubled.
For example, "\\\u0022" will be "\\\\\\u0022" but I expects only "\" just
before "u" will be escaped if the number of "\" is odd.
