Basic authentication does not support using UTF-8-encoded characters in IIS 6.0

INTRODUCTION

In Internet Information Services 6.0, Basic authentication does not support using UTF-8-encoded characters in the following parts of an HTTP request:
  • The domain name
  • The user name
  • The password
An HTTP request that uses UTF-8-encoded characters and Basic authentication fails unless the client computer and the server that is running IIS 6.0 are configured to use the same system locale setting.

MORE INFORMATION

Typically, the scheme that is used to convert the domain name, the user name, and the password to Unicode does not support decoding UTF-8-encoded characters. However, the scheme supports decoding UTF-8-encoded characters if the code page on the client computer and the code page on the server that is running IIS 6.0 match.
