Hi Iâm experiencing a problem when I try to encode an URL with latin characters with accents or circumflex. The example is: â âZnPercentEncoder new decode: 'Neuquén, Neuquén Province, Argentina' The IETF standard provides these definitions: https://www.ietf.org/rfc/rfc3986.txt https://tools.ietf.org/html/std63 the implementation ZnPercentEncoder, decode: stringStream to: byteStream could be changed to accept characters below 256. (char charCode < 256 instad of char charCode < 128)? decode: stringStream to: byteStream | char | self decodePlusAsSpace. [ stringStream atEnd ] whileFalse: [ ((char := stringStream next) == $+ and: [ decodePlusAsSpace ]) ifTrue: [ byteStream nextPut: 32 ] ifFalse: [ char == $% ifTrue: [ byteStream nextPut: (self readHexFrom: stringStream) ] ifFalse: [ char charCode < 128 ifTrue: [ byteStream nextPut: char charCode ] ifFalse: [ self errorAsciiCharacterExpected ] ] ] ]
