Research direction

Start by locating the OpenAPI schema and rendered description for the check-run output.summary and output.text fields under the /repos/{owner}/{repo}/check-runs endpoint. Confirm how the 65535 maxLength is represented and determine the precise unit wording needed; done means the schema and endpoint documentation no longer leave the limit ambiguous.

Schema Inaccuracy

The /repos/{owner}/{repo}/check-runs's parameter body.output.summary, body.output.text describe a max length of 65535 "characters" in their description.

The summary of the check run. This parameter supports Markdown. Maximum length: 65535 characters."

The the encoding of a "character" is not specified, which can lead to confusion, as described in https://github.com/github/docs/issues/35252. Based on that issue, "character" in this case is seemingly referring to a 1-byte ascii making the "character" limit a "byte limit" in practice. However since utf8 is supported and rendered, the character count can be far less in practice, especially for check-runs which use non-latin languages as their output.

This confusion might be considered to be clarified since the schema specifies the field's output.summary.maxLength. However OpenAPI is also unclear about if maxLength refers to bytes, characters of a given encoding, etc, and also the maxLength field is not rendered in the Github API docs.
