Re: [Pharo-users] Problem with Traditional and Simplified Chinese parsing in Pharo

Hi,

I am currently parsing lua and JSON-like file in Pharo. They contain both Simplified and Traditional Chinese characters for comments and for strings displayed in the UI. Lua files are parsed correctly. However the JSON-like files aren't.

In attachment I put one of the problematic file with Simplified chinese characters (I've also copied the file at the end of the mail). The problem can be shown as follow in Pharo:

'schinese.txt' asFileReference readStream contents

The contents function sends a UTF8InvalidText 'Invalid utf8 input detected' error. However my text editor correctly displays the file and it is correctly parsed by the Lua runtime (The program parsed has been deployed in production for years and works fine).

What can I do to parse this file correctly from Pharo ?

Hi, Here is how we manage encoding in Moose following Sven's advices. We detect the encoding of a file with this code: [ self fileReference binaryReadStreamDo: [ :in | (ZnCharacterEncoder detectEncoding: in upToEnd) identifier ] ] on: ZnCharacterEncodingError do: [ nil ] It is not bullet proof but I never got a problem since we use it. Then to read a file we do this: self fileReference binaryReadStreamDo: [ :in | (ZnCharacterReadStream on: in encoding: self encoding) upToEnd ] Here, self encoding return the result of the previous snippet. Or you can use it this way: ZnCharacterEncoder detectEncoding: ((FileLocator desktop / 'some.data') binaryReadStreamDo: [ :in | in upToEnd ]). (FileLocator desktop / 'some.data') binaryReadStreamDo: [ :in | | bytes encoder | bytes := in upToEnd. encoder := ZnCharacterEncoder detectEncoding: bytes. encoder decodeBytes: bytes ].

Thanks,

Below is the file content, non Chinese people may not have the font to display the characters, note that I have no idea what is written in Chinese (Please don't hold me responsible if there are offending contents):
