在修改范例程序hello led中的参数时(i<200000)为(i<500000)时出现下面的错误提示.

Save could not be completde.

Reason:

     Some characters cannot be mapped using "GBK" character encoding.

Either change the encoding or remove the characters which are not supported by the  "GBK" character encoding. 

“    Some characters cannot be mapped using "GBK" character encoding.”

ide提示表达式中有不支持的字符。

我还没有遇到过这种问题，估计和你的系统有关，你不妨换一种输入法试一下，实在不行用多重循环来实现吧。

也有可能和系统有关。
