 ICU provides multiple text access interfaces which were added over time. If
 simple strings cannot be used, then consider the following:
 
-1.  [UText](utext.md): Added in ICU4C 3.4 as a technology preview. Intended to
-    be the strategic text access API for use with ICU. C API, high performance,
-    writable, supports native indexes for efficient non-UTF-16 text storage. So
-    far (3.4) only supported in BreakIterator. Some API changes are anticipated
-    for ICU 3.6.
