Capitolo 362. Entità ISO ed entità HTML gestite da Alml
Nel seguito vengono mostrate alcune tabelle e alcuni listati che riportano lo stato attuale della capacità di Alml di rappresentare le entità ISO e le entità HTML standard. A seconda del tipo di composizione utilizzato si può notare la presenza o l'assenza di alcuni simboli.
In questi elenchi sono annotati anche i punti di codifica corrispondenti; tuttavia, è possibile notare che uno stesso punto di codifica può essere associato a entità differenti.
|
Si osservi che le attribuzioni ai punti di codifica possono essere errate, pertanto potrebbero cambiare in futuro.
|
È importante osservare che i caratteri riferiti a dei linguaggi non latini, richiedono la selezione del linguaggio stesso, eventualmente anche con l'uso degli elementi span e div. Questo dovrebbe chiarire il significato della presenza di due gruppi di alfabeti greci: ISOgrk1 e ISOgrk2 sono riferiti alla lingua greca, mentre ISOgrk3 e ISOgrk4 sono alfabeti simbolici indipendenti dal linguaggio con il quale vengono utilizzati.
|
In generale, dal momento che l'insieme di caratteri universale non fa queste distinzioni, se il sorgente SGML viene scritto utilizzando codici che possono essere associati a simboli in contesti differenti, viene scelto prima quello che è attribuibile a una lingua. Per esempio, il punto di codifica U+03B1 viene convertito nella lettera greca «α» corrispondente alla macro &agr;, che però deve essere usata nell'ambito della lingua greca: <span lang="el">α</span>. In mancanza di questa accortezza, nella composizione per la stampa si otterrebbe la lettera latina «a», che rappresenta la sua traslitterazione.
|
362.1
Alfabeti simbolici
Gli elenchi di questa sezione riguardano gli alfabeti simbolici, che non dovrebbero dipendere dal linguaggio utilizzato. Tuttavia, in pratica, simboli come «+», «=», «&» e «@», possono apparire diversi dal solito, quando si usano linguaggi che prevedono un alfabeto non latino.
