escaped comma cannot be used in measurement names

[localvar]

Describe the bug（Bug 描述）

According to line protocol, comma can be used in measurement names after an escape.

But when using this character in openGemini, it reports "invalid measurement name".

To Reproduce（Bug 复现步骤）

> create database db0
> use db0
> insert cp\,u,host=server1 value=10
ERR: {"error":"partial write: invalid measurement name: cp,u dropped=1"}

Note the above insert statement can be executed successfully in influxdb.

Currently, some transfer characters and special characters cannot be added to measurement names.
openGemini unsupport

Currently, some transfer characters and special characters cannot be added to measurement names. openGemini unsupport

could this be documented, especially, which characters are included in the "some transfer characters and special characters"? Because this documentation says openGemini uses the same line protocol as influxdb.
