在开发中试了下，codePoint == 0x0) || (codePoint == 0x9) || (codePoint == 0xA)
|| (codePoint == 0xD)
|| ((codePoint >= 0x20) && (codePoint <= 0xD7FF))
|| ((codePoint >= 0xE000) && (codePoint <= 0xFFFD))
|| ((codePoint >= 0x10000) && (codePoint <= 0x10FFFF)
这个方法能过滤掉大部分 但还是不能过滤全部 比如华为的输入法
调试输出下无法过滤的codePoint，把它添加到这个判断范围中
