mysql2date does not get weekday/month abbreviations from locale

[nbachiyski]

The mysql2date function (wp-includes/functions.php) does not use the $month_abbrev and $weekday_abbrev arrays, but instead gets the first 3 characters of the day/month name. In English, of course, it works quite perfectly, but when using localized month/date names there are two problems:

1) In some languages the abbreviations are much or less different (not exactly 3 symbols, not exactly the first three and so on)

2) substr is not unicode safe. As a result we get the first three bytes but, when the string is in utf8 I get the first character and a half :)
