Feature #1667: IO#codepoints, IO#each_codepoint, and StringIO

• Status: Closed
• Assignee: -
• Target version: -

[marcandre (Marc-Andre Lafortune)]

Almost all "iterators" of String are present in IO and StringIO: #each_char, #each_byte, #each_line and their corresponding #chars, #bytes, #lines. Only #each_codepoint and #codepoints are not defined in IO and StringIO.

Unless there is a compelling reason not to, it would be useful if these were defined. This would mirror the coherence with all other each_* methods that exist in both String, IO and StringIO.

Why is "an incomplete character before EOF" ignored?

		if (more_char(fptr) == MORE_CHAR_FINISHED) {
		    clear_readconv(fptr);
		    /* ignore an incomplete character before EOF */
		    return io;
		}
