T\u00eb gjitha filloi me nj\u00eb skenar t\u00eb shkurt\u00ebr, i cili duhej t\u00eb bashkonte informacionin mbi adresat e-mail<\/em> e punonj\u00ebsve, t\u00eb marr\u00eb nga lista e p\u00ebrdoruesve t\u00eb d\u00ebrgimit t\u00eb postave, me pozitat e punonj\u00ebsve, t\u00eb marr\u00eb nga baza e t\u00eb dh\u00ebnave t\u00eb departamentit t\u00eb burimeve njer\u00ebzore. T\u00eb dyja listat ishin eksportuar n\u00eb skedar\u00eb tekstual\u00eb n\u00eb kodimin Unicode UTF-8<\/em> dhe ruajtur me p\u00ebrfundimet e linjave n\u00eb Unix.<\/p>\n

P\u00ebr t\u00eb bashkuar, skedar\u00ebt u sortuan nga komanda Unix sort<\/em> dhe u paraqit\u00ebn si hyrje n\u00eb programin Unix bashkohu<\/em>, i cili p\u00ebrfundoi papritur me nj\u00eb gabim: <\/p>\n

<\/p>\n
Shikimi i rezultatit t\u00eb renditjes me sy tregoi se n\u00eb p\u00ebrgjith\u00ebsi renditja \u00ebsht\u00eb korrekte, por n\u00eb rastet e emrave t\u00eb p\u00ebrputhur meshkuj dhe femra, emrat femra shkojn\u00eb para atyre meshkujve:<\/p>\n

Duket si nj\u00eb gabim i renditjes n\u00eb Unicode ose si nj\u00eb shfaqje e feminizmit n\u00eb algoritmin e renditjes. E para, sigurisht, \u00ebsht\u00eb m\u00eb e besueshme.<\/p>\n

Ta l\u00ebm\u00eb p\u00ebr tani bashkohu<\/em> dhe t\u00eb p\u00ebrqendrohemi n\u00eb sort<\/em>. T\u00eb p\u00ebrpiqemi t\u00eb zgjidhim problemin me metod\u00ebn e provave. P\u00ebr t\u00eb filluar, t\u00eb ndryshojm\u00eb lokalitetin nga en_US<\/em> n\u00eb ru_RU<\/em>. P\u00ebr renditjen do t\u00eb ishte mjaft t\u00eb vendosnim variablin e ambientit LC_COLLATE<\/em>, por nuk do t\u00eb jemi t\u00eb kopert\u00eb:<\/p>\n

T\u00eb p\u00ebrpiqemi t\u00eb rikodojm\u00eb skedar\u00ebt n\u00eb nj\u00eb kodim nj\u00eb-byte: <\/p>\n

P\u00ebrs\u00ebri nuk ndodhi asgj\u00eb.<\/p>\n

Nuk ka \u00e7far\u00eb t\u00eb b\u00ebjm\u00eb, do t\u00eb duhet t\u00eb k\u00ebrkojm\u00eb zgjidhje n\u00eb internet. Drejt p\u00ebr mbi emrat rus\u00eb nuk ka asgj\u00eb, por ka pyetje rreth \u00e7udit\u00ebris\u00eb s\u00eb rendit. Ja, p\u00ebr shembull, nj\u00eb problem i till\u00eb: unix sort i trajton karakteret ‘-‘ (dash) si t\u00eb paduksh\u00ebm<\/a><\/noindex>. N\u00ebse e p\u00ebrmbledhim, at\u00ebher\u00eb fjalit\u00eb "a-b", "aa", "ac" renditen si "aa", "a-b", "ac".<\/p>\n
<\/p>\n
P\u00ebrgjigjja \u00ebsht\u00eb standarde kudo: p\u00ebrdorni lokalitetin programues "C"<\/em> dhe do t\u00eb jeni t\u00eb lumtur. Provo:<\/p>\n

$> LANG=C sort buhg.txt > buhg.srt\n$> LANG=C sort mail.txt > mail.srt\n$> LANG=C join buhg.srt mail.srt > result<\/code><\/pre>\n

Ka funksionuar pa gabime, si\u00e7 e premtoi interneti. Edhe kjo p\u00ebrkund\u00ebr \u0401lkina n\u00eb rreshtin e par\u00eb.<\/p>\n
<\/p>\n
Duket se problemi \u00ebsht\u00eb zgjidhur, por p\u00ebr \u00e7do rast do t\u00eb provojm\u00eb nj\u00eb kodim tjet\u00ebr rus\u2014at\u00eb nga Windows. CP1251<\/em>:<\/p>\n

Rezultati i renditjes, si\u00e7 \u00ebsht\u00eb e \u00e7uditshme, do t\u00eb p\u00ebrputhet me lokalitetin "C"<\/em>, dhe e gjith\u00eb shembulli, p\u00ebrkat\u00ebsisht, kalon pa gabime. \u00cbsht\u00eb nj\u00eb mister i \u00e7uditsh\u00ebm.<\/p>\n
<\/p>\n
Nuk m\u00eb p\u00eblqen misteri n\u00eb programim, pasi zakonisht maskon gabimet. M\u00eb duhet t\u00eb merrem seriozisht me pyetjen se si funksionon sort<\/em> dhe \u00e7far\u00eb ndikon LC_COLLATE<\/em> .<\/p>\n
<\/p>\n
N\u00eb fund do t\u00eb p\u00ebrpiqem t\u00eb p\u00ebrgjigjem n\u00eb pyetje:<\/p>\n
