/* NOTE: We assume that most strings passed around this library are
* UTF-8 (modified or standard) and not platform encoding.
* Before sending any strings to the "system" (e.g. OS system
* calls, or system input/output functions like fprintf) we need
* to make sure that the strings are transformed from UTF-8 to
* the platform encoding accepted by the system.
* UTF-8 and most encodings have simple ASCII or ISO-Latin
* characters as a subset, so in most cases the strings really
* don't need to be converted, but we don't know that easily.
* Parts of messages can be non-ASCII in some cases, so they may
* include classnames, methodnames, signatures, or other pieces
* that could contain non-ASCII characters, either from JNI or
* JVMTI (which both return modified UTF-8 strings).
* (It's possible that the platform encoding IS UTF-8, but we
* assume not, just to be safe).
