请问一个UNICODE的有关问题，
请教一个UNICODE的问题，高手请进！
从API得到一个XML，里面有汉字什么的，还有“\uE40A”和“\uE40B”这样的标识符，请问用PHP如何在文本中找到这些标识符？
下面是一个例子：关键字“掉渣饼”两侧就是这两个标识符，但是PHP似乎很难处理这个问题
------解决方案--------------------
UTF-8字符，这些字符超出了字体库的范围。
------解决方案--------------------
unicode的e000-f8ff码段属于“用户私有”
就是说unicode组织并不在该码段定义任何字符，预留给用户自行使用
所以你所说的这些字符是api自定义的，看来是边界符，请参考你的api说明文档
------解决方案--------------------
正则，/[\uE000-\uF8FF]/u，逐个找出来替换为你需要的
