In the past we had a special function to do mb_encode_mimeheader correctly.
Since PHP 8.2 this works perfectly fine, so all the code was removed and
replaced with just the normal "mb_encode_mimeheader" call with the same
settings as before:
- set global encoding to parameter
- run encoding with charset, 'B' for transfer and use the line break given in parameter
- reset the global encoding to previous set
string: if it is stringable in anyway, set string (it converts)
this is not check IF it is a string value as it was before
int/float: same, if it is numerc it will be convert to int or float
All other stay the same
Note "set ..." imply to set, and not to convert to 0 if it is int
string that can be covnerted to int
All Color methods will throw Exceptions:
LengthException,
InvalidArgumentException,
UnexpectedValueException
instead of returning bool: false
All methods will return valid color data as expected only
