  29  * \brief C API: Transliterator
  30  *
  31  * <h2> Transliteration </h2>
  32  * The data structures and functions described in this header provide
  33  * transliteration services.  Transliteration services are implemented
  34  * as C++ classes.  The comments and documentation in this header
  35  * assume the reader is familiar with the C++ headers translit.h and
  36  * associated documentation.
  37  *
  38  * A significant but incomplete subset of the C++ transliteration
  39  * services are available to C code through this header.  In order to
  40  * access more complex transliteration services, refer to the C++
  41  * headers and documentation.
  42  *
  43  * There are two sets of functions for working with transliterator IDs:
  44  *
  45  * An old, deprecated set uses char * IDs, which works for true and pure
  46  * identifiers that these APIs were designed for,
  47  * for example "Cyrillic-Latin".
  48  * It does not work when the ID contains filters ("[:Script=Cyrl:]")
  49  * or even a complete set of rules because then the ID string contains more
  50  * than just "invariant" characters (see utypes.h).
  51  *
  52  * A new set of functions replaces the old ones and uses UChar * IDs,
  53  * paralleling the UnicodeString IDs in the C++ API. (New in ICU 2.8.)

 488  * @param trans the transliterator
 489  * @param text a pointer to a buffer containing the text to be
 490  * transliterated on input and the result text on output.

 493  * zero-terminated.  Upon return, the new length is stored in
 494  * *textLength.  If textLength is NULL then the string is assumed to
 495  * be zero-terminated.
