(String str) |
yoix.string |
| |
Returns the number of bytes resulting from a UTF-8 encoding of
str.
The UTF-8 encoding itself is not performed.
One instance where this information is useful occurs
when determining if strings in a
ZipEntry
will exceed the allowed maximum byte lengths.

| Example: |
Refer to the documentation for
offsetBytes
to see an example of
offsetSupported
usage.

| Example: |
The following script determines the number of bytes needed for a
UTF-8 encoding of some German text.
import yoix.stdio.*;
import yoix.string.*;
String joy = "O, Freunde, nicht diese Töne!\n\
Sondern laß uns angenehmere\n\
anstimmen, und freudenvollere.\n\
\n\
Freude, schöner Götterfunken\n\
Tochter aus Elysium.\n\
Wir betreten freuertrunken,\n\
Himmlische, dein Heiligtum!\n\
Deine Zauber binden wieder,\n\
Was die Mode streng geteilt;\n\
Alle Menschen werden Brüder,\n\
Wo dein sanfter Flügel weilt.\n";
fprintf(stdout,
"String Length: %d\nUTF-8 Length: %d\n",
joy@length, utf8len(joy));
The result on standard output is shown below:
String Length: 312
UTF-8 Length: 318
