Details:

In version 1.4.1 of the mapping package, the str2angle function fails to parse
strings containing the degree (°) symbol.  For instance :


> pkg load mapping
> str2angle ("22°52'44.25\"")
ans =  Inf


With the patch attached to this bug report, we get this result:


> str2angle str2angle ("22°52'44.25\"")
ans =  22.879


This is the reason the unit tests are failing:


octave:5> test str2angle
***** shared tst, res
 tst = '191E21''3.1"\n12e 22''33.24"\n13E 23'' 33.344"\n14w24'' 33.4444"\n';
 tst = [tst '15S25''33.54444"\n16W26''33.644444''''\n17s27''33.7444444"\n'];
 tst = [tst
'18N28''33.84444444"\n19d29m33.944444444s\n20D20M33.04444444Se\n'];
 tst = [tst '21°51''4.1"\n22°52''44.25"\n23° 53''33.34"\n24°54''
33.44"N\n'];
 tst = [tst '25° 55'' 33.544"\n26°56''33.644''''S\n27°57'' 33.744''''\n'];
 tst = [tst '28°58''33.844"w'];
 tst = strrep (tst, '\n', char(10));
 res = [191.351, 12.376, 13.393, -14.409, -15.426, -16.443, -17.459, 18.476,

        27.959, -28.976];
