wp_texturize converting x to × is too greedy

[mtdewvirus]

Converting x to × in wp_texturize() converts too much. Strings like 4x4 and 4x20=80 should be converted but there are a lot of times when x is in a model number such as rt2x00 where the character should not be converted to a multiplication symbol.

A quick method for this, would be to have the regex matching word boundaries: /\b(\d+)x(\d+)\b/ and that seems to work as expected:

Eg:

"4x4 and 4x20=80 ....2x2, but not A4x4 and  rt2x00";
string '4×4 and 4×20=80 ….2×2, but not A4x4 and  rt2x00'

(In [14144]) Make (\d)x(\d) texturization less greedy, requires a word boundary either side of the phrase. See #12118

Since there's a fix in, it seems this ticket never got closed. So closing.
