Unable to compile FrenchAnalyser and DutchAnalyser

[DZISIAK Jean-Paul]

Hello,

 

I’m trying to recompile the FrenchAnalyser and DutchAnalyser but I have the
following errors (among many others of the same type):

 

.................................

                        private boolean isVowel(char ch) {

                        switch (ch)

                        {

                                   case 'â':

                                   case 'Ã ':

                                   case 'ë':

                                   case 'é':

                                   case 'ê':

                                   case 'è':

                                   case 'ï':

                                   case 'î':

                                   case 'ô':

                                   case 'ü':

.................................

                                   

 

The IDE says “Too many characters in character litteral” and the compilation
“unclosed character literal’

 

Help would be very appreciated !
