- * Wrapper for charset conversions.
- *
- * In most languages, this calls through to standard system iconv(), but
- * for Esperanto we're also adding a special pseudo-charset to convert
- * accented characters to/from the ASCII-friendly "X" surrogate coding:
- *
- * cx = ĉ cxx = cx
- * gx = ĝ gxx = gx
- * hx = ĥ hxx = hx
- * jx = ĵ jxx = jx
- * sx = ŝ sxx = sx
- * ux = ŭ uxx = ux
- * xx = x
- *
- * http://en.wikipedia.org/wiki/Esperanto_orthography#X-system
- * http://eo.wikipedia.org/wiki/X-sistemo
- *
- * X-conversion is applied, in either direction, between "utf-8" and "x" charsets;
- * this comes into effect when input is run through $wgRequest->getText() and the
- * $wgEditEncoding is set to 'x'.
- *
- * In the long run, this should be moved out of here and into the client-side
- * editor behavior; the original server-side translation system dates to 2002-2003
- * when many browsers with really bad Unicode support were still in use.
- *
- * @param string $in input character set
- * @param string $out output character set
- * @param string $string text to be converted
- * @return string
