Hello,

some of my customers can't confirm their E-Mail addresses. They get errors when clicking the links. One of the users forwarded me the confirmation E-Mail; it seemed to be ok.

After inspecting the audit logs, I found out that user and tenant ids are correct. However, the tokens seem to contain unicode characters. For example:

`"token": "CfDJ8DKAitCAIvVDuLO5ZU057RuhcCbm1aNCntlJiDXp\u002BPueFsoWE920CmZX9vL2kF\u002BbzMET\u002BNJYJzUJHUVDpFOblBu4T1PaGUui\u002BEhNHZAJqMjdsz15CXpkSglNFts9Mz525IKkkjZ\u002BaZeghXIeI8jgnPdPtaODHGrGBSysPMry/TQMzX5EKLDLEvgPivqiMSEGuRHP5tG9WcVBqiozHqfHxt9V\u002BDZOdnK2uRt2nfz9KRygvAdwOhwzO7UdwjLwLR5uOg=="`

I'm not sure whether these \u002... characters belong to the token? Unfortunately, I couldn't find where the tokens are stored in the database (AbpUserTokens table is empty?) so I didn't have a chance to compare then.

Any idea?

Thanks in advance and best regards Claus
