什么都是Watson服务不支持的符号，以避免BadRequestException

Question

我目前正在使用IBM Watson的Java SDK文本到语音转换API

代码如下

TextToSpeech textToSpeech = new TextToSpeech();
textToSpeech.setUsernameAndPassword(username, password);
ServiceCall<InputStream> inputStreamServiceCall = textToSpeech.synthesize(text, Voice.EN_ALLISON, AudioFormat.OGG);
InputStream in = inputStreamServiceCall.execute();

将文本转换为语音时会出现异常

  

com.ibm.watson.developer_cloud.service.exception.BadRequestException：           在com.ibm.watson.developer_cloud.service.WatsonService.processServiceCall（WatsonService.java:416）   〜[java的SDK-3.3.0.jar：NA]           在com.ibm.watson.developer_cloud.service.WatsonService $ 1.execute（WatsonService.java:179）   〜[java的SDK-3.3.0.jar：NA]

我通过用空格替换下列符号“”© - ''▒“{} |`\来解决这个问题。

请告知watson服务不支持的所有符号？

将com.ibm.watson.developer_cloud java-sdk升级到更高版本.latest是3.8.0。在java-sdk-3.3.0.jar中，在对watson进行API调用时，某些字符未正确编码。
