【Android】okhttp使用3.12.12，特殊字符（如中文）文件名会导致Crash~

**Crash stack info**

通过okhttp3.12.12源码可以发现，如果文件包含特殊字符（比如中文）就抛异常，但是在上一层函数中并没有捕获和进一步往上throw：
```java
public Builder add(String name, String value) {
checkName(name);
checkValue(value, name);
return addLenient(name, value);
}

static void checkValue(String value, String name) {
if (value == null) throw new NullPointerException("value for name " + name + " == null");
for (int i = 0, length = value.length(); i < length; i++) {
char c = value.charAt(i);
if ((c <= '\u001f' && c != '\t') || c >= '\u007f') {
throw new IllegalArgumentException(Util.format(
"Unexpected char %#04x at %d in %s value: %s", (int) c, i, name, value));
}
}
}
```
