印刷可能でない文字をCF8でSerializeJSONを回避するには？

Question

SerializeJSONは印刷不可能な文字（つまりASCII 21）を使用してJSONを作成します

これは無効なJSONです。どうすればこれを回ることができますか？

印刷できない文字を削除する正規表現は機能しますか？

印刷可能でない文字を削除する正規表現はありますか？

この単純な解決策はcffeed用に作成されましたが、問題は非常に似ています。

まず、JavaライブラリStringEscapeUtils（Commons Lang API）を使用しようとしましたが、コンテンツを正しくエスケープしませんでした。 XMLにはお勧めです。

このcfcメソッドは私のために働きます。多分あなたを助けるでしょう。

<cffunction name="cleanXmlString" access="public" returntype="any" output="false" hint="Replace non-valid XML characters"> 
    <cfargument name="dirty" type="string" required="true" hint="Input string"> 
    <cfset var cleaned = "" /> 
    <cfset var patterns = "" /> 
    <cfset var replaces = "" /> 

    <cfset patterns = chr(8216) & "," & chr(8217) & "," & chr(8220) & "," & chr(8221) & "," & chr(8212) & "," & chr(8213) & "," & chr(8230) /> 
    <cfset patterns = patterns & "," & chr(1) & "," & chr(2) & "," & chr(3) & "," & chr(4) & "," & chr(5) & "," & chr(6) & "," & chr(7) & "," & chr(8) /> 
    <cfset patterns = patterns & "," & chr(14) & "," & chr(15) & "," & chr(16) & "," & chr(17) & "," & chr(18) & "," & chr(19) /> 
    <cfset patterns = patterns & "," & chr(20) & "," & chr(21) & "," & chr(22) & "," & chr(23) & "," & chr(24) & "," & chr(25) /> 
    <cfset patterns = patterns & "," & chr(26) & "," & chr(27) & "," & chr(28) & "," & chr(29) & "," & chr(30) & "," & chr(31) /> 

    <cfset replaces = replaces & "',',"","",--,--,..." /> 
    <cfset replaces = replaces & ",-, , , , , , , " /> 
    <cfset replaces = replaces & ", , , , , , " /> 
    <cfset replaces = replaces & ", , , , , , " /> 
    <cfset replaces = replaces & ", , , , , , " /> 

    <cfset cleaned = ReplaceList(arguments.dirty, patterns, replaces) /> 

    <cfreturn cleaned /> 

</cffunction>
