bash - how to use alternate vt100 character sets -

-

according http://www.in-ulm.de/~mascheck/various/alternate_charset/ esc+)+0 make g0 set sequence table used or something. http://www.vt100.net/docs/vt100-ug/table3-9.html seems provide description of characters should appear when "table" in use. eg.

<?php echo "\x1b)0" . chr(0147)

...should result in ± appearing on console understand it. no ± appearing. instead what's appearing g.

so it's not entirely clear me how use in cli environment make ± appear.

any ideas?

try ( instead of ):

<?php echo "\x1b(0" . chr(0147) ?>

( sets charset used in default "g0" slot, whereas ) effects "g1" slot. shift-in/shift-out escape sequences switch between 2 slots.

in mean time, recommend forget legacy stuff , use proper stateless utf-8 , ± sign.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
