datagrid can't show illegal character.

[frankgao]

Hi,
There can't display data with the datagrid when json data include illegal character.
How can realize display illegal character in some special needs.

Code:

{"total":1,"rows":[{"logid":"97033","contents":"\0","ip":"127.0.0.1","builddate":"2015-10-06 17:51:34","emname_st":"abc","sysfunname_cn":""}]}

I found with google that '\0' is not allowed in json string.

I wrote a small example:
if I force in the json string the character '\0' the datagrid is not populated,
but if I create the json string on server side with the "to_json" function (in my case I use perl) the character '\0' is translated to '\u0000' and the datagrid is displayed correctly.

How do you create the json string on server side and which other special characters are not displayed correctly ?

Regards.
