I have a Groovy list that holds the unicode representation of select foreign language characters, something like this simplified version:
def myList = ['*\u00E4*','\u00D6','\u00F8'] I have built myself a Groovy map that is the crosstabulation of characters by count in an incoming document, so my map looks something like this: crossTab = ["a" : "16736", "b" : "192", " * รค *" : "18"] The foreign language characters in this map that are in the set of keys often have extra whitespace around them, and for certain languages there is a weird "right to left" thing going on that I don't quite fully understand. My objective: iterate through my list, return true if the element from the list is found as a key in the map, and return the count - the map value for that key - if the key is found. My problem: my lookup is failing to return any hits right now. I know that some of these foreign language characters are in my data. I suspect my lookup is failing because the keys are not clean representations of the foreign language characters. How do I modify my keys using Groovy to trim them of leading and trailing whitespace? Since my element from my list is expressed as unicode, how would I convert the trimmed key representation to unicode using Groovy? Thank you in advance for any help.
