[Building Sakai] BLTI : BaseString generation

[Yegeneswari Nagappan]

Hi,

We are using BLTI tool in Sakai 2.9 and need some clarification on how the BaseString is generated for parameters with special characters in it. The launch from a site with title "French d’économie" (has accent character in title)failed because the BaseString that got generated for the title on Sakai is different from the value on the BLTI Producer system.

Should the string be utf-8 encoded character set prior to Step 1 mentioned in OAuth 1.0 Spec for Percent-encoding strings (http://tools.ietf.org/html/rfc5849#section-3.6) ?

On Sakai side, the string "French d’économie" was used directly in Step 1 where as on the BLTI producer system, the utf-8 encoded character set i.e "French d’économie" was used in Step 1.

Can you please confirm if Sakai is implemented as per spec.

Thanks for your help!

P.S :I used this site http://coderstoolbox.net/string/ to find the utf-8 encoded character set for given string.
