Bug #6650: Fixing win32ole test errors

• Status: Closed

Since FileSystemObject is limited only to ANSI and UTF-16LE encoding tests shouldn't try to use other encodings since they will certainly fail. Instead UTF-16 encoding should be used to check whether writing/reading to/from FSO is properly handled. Attached is a patch that fixes this.

suke,

Can you tell us a bit more about WIN32OLE.locale and WIN32OLE.codepage prior running the tests? what is the default locale (chcp)?

These test work under WIN32OLE.codepage 1252 and 65001, so I'm wondering why they are not in your case.

I had same failure on Win7 with chcp 932(default), 1252 and 65001. I guess it depends on Windows system default encoding.
If I change the string from UTF-8 to UTF-16LE, the test works fine for me.
UTF-16LE or ASCII String might be better. I attached the patch.

Hiroshi, I don't fully follow the rationale in the patch.

You're encoding the string first as UTF-16LE and then force encoding as UTF-16 when sending it to FSO.

AFAIK FSO Only understands ANSI and UTF-16LE.

Also, by doing force_encoding, you're changing test_str to the new encoding and not preserving the original.

I couldn't find WIN32OLE in the list of maintainers, but will be great to hear his comments.

I did force_encoding("UTF-16") because FSO doesn't allow UTF-16LE encoding and an error occurs. Bosko's patch also uses UTF-16 instead of UTF-16LE. force_encoding doesn't change binary representation of test_str.

Masaki,

Can you confirm tests pass after applying Hiroshi's patch?

Thank you.
