Hi Monks,

My goal is to have any character which is not within the GSM 7-bit default alphabet, to be removed from a given string. Basically it is a mixture of regular/accented/greek letters and some ponctutation. The complete character set is the first table at this URL: https://en.wikipedia.org/wiki/GSM_03.38 :

The list is:

@£$¥èéùìòÇØøÅå&#916;_&#934;&#915;&#923;&#937;&#928;&#936;&#931;&#920;&#926;ÆæßÄÖÑܧ¿äöñüàÉ !"#¤%&'()*+,-./:;<=>?¡A-Za-z0-9

Of course this is not working:

 $str =~ s/[^\@£\$¥èéùìòÇØøÅå&#916;_&#934;&#915;&#923;&#937;&#928;&#936;&#931;&#920;&#926;ÆæßÉ !"#¤%\&\'\(\)\*\+\,\-\.\/0-9:;<=>\?¡A-ZÄÖÑܧ¿a-zäöñüà]//g;

I searched for hours on how to do this and I am seeking your knowledge on which direction to take to accomplish this. (it seems that the site replaced some of the above characters with HTML code, sorry for this)

Thank you
