The "char" type - valid values?

Hi,

The spec says: “Single character value, can include any alphanumeric character or punctuation except the delimiter”.

The mentioning of the delimiter confuses me as SOH isn’t an alphanumeric character in the first place. So which values are valid?

Alphanumeric characters as recognized by the isalnum() function plus punctuation characters?

Or any printable character as recognized by isprint()?

Thanks,
jules

Jules the only value that cannot be specified in type char is 0x01 (SOH). We can look at addressing the language ambiguity in the next draft.

Hi Jim,

Somewhere or other there’s a post from me on here about the use of character sets in FIX 4.2 string fields. The 4.2 spec is a bit unclear - perhaps you could clarify this as well?

Thanks!

Captured the issue with lack of clarity in terms of the char datatype.
I have created Jira item SPEC-536 to consider revising the description.
