Sales Cloud for Slack: Multi-Byte Characters Not Supported in Sales Channel Names.

Fecha de publicación: Nov 13, 2025
Descripción

Sales Cloud for Slack allows teams to collaborate on deals within Slack channels. When creating a new sales channel directly from a Salesforce record, the channel name must follow Slack's naming restrictions, which do not support multi-byte characters like Japanese (日本語), Korean (한국어), or Chinese (中文) characters.

When you try to create a sales channel and a new Slack channel at the same time using the [Link Slack Channel] action on a Salesforce record page, the following error will be displayed. This is because creating Slack channels with a name containing multi-byte characters (such as Japanese, Korean, and Chinese) is not supported. 

-----

Channel names can't contain spaces, periods, or most punctuation.

Solución

Because Slack does not support multi-byte characters in channel names at the platform level, create the channel in Slack first, then link it to the Sales Cloud record.

After creating a Slack channel with a name containing multi-byte characters in Slack, please link that existing Slack channel when you create the sales channel from the [Link a Slack Channel] action.

To use multi-byte characters in your sales channel name, first create the Slack channel manually in Slack, then link it to your Salesforce record. This bypasses the character restriction in the Sales Cloud for Slack channel creation flow.

Setup Instructions :

1,Create a channel with a name containing multi-byte characters in Slack.

2,Open a record in Salesforce and click [Link a Slack Channel].

3,Select the existing channel and specify the one you created.
