com.ibm.icu.lang.UScriptRun
UScriptRun is used to find runs of characters in the same script, as defined in the UScript class. It implements a simple iterator over an array of characters. The iterator will assign COMMON and INHERITED characters to the same script as the preceeding characters. If the COMMON and INHERITED characters are first, they will be assigned to the same script as the following characters. The iterator will try to match paired punctuation. If it sees an opening punctuation character, it will remember the script that was assigned to that character, and assign the same script to the matching closing punctuation. No attempt is made to combine related scripts into a single run. In particular, Hiragana, Katakana, and Han characters will appear in separate runs. Here is an example of how to iterate over script runs:
```
 void printScriptRuns(char[] text) { UScriptRun scriptRun = new UScriptRun(text); while (scriptRun.next()) { int start  = scriptRun.getScriptStart(); int limit  = scriptRun.getScriptLimit(); int script = scriptRun.getScriptCode(); System.out.println("Script \"" + UScript.getName(script) + "\" from " + start + " to " + limit + "."); } } 
```
