Changes between Initial Version and Version 1 of Ticket #34939, comment 22

initial	v1
12	12	TinyMCE has a habit of converting spaces (0x20) into non-breaking spaces (0xa0). It's done this for quite a while. Reproducing it is easy: type in a number of spaces in a row. Every other one will become a non-breaking space (0xa0).
13	13
14		The regular expression pointed out by @dd32 above does not recognize 0xa0 as valid separators. Seems like either 0xa0 should be added as a possible character not allowed in an shortcode/attribute name in order to prevent this issue, or the expressions reconsidered entirely.
