Encoding differences between tr (ubuntu) and tr (mac) -

- 

echo – | tr ’ x

on mac: correctly prints –

on ubuntu 10.10: prints xx�

why?

for reference, first character 'en dash' (u+2013), second 'right single quotation mark' (u+2019)

edit: use perl instead. magic incantation use is:

perl -csd -p -mutf8 -e 'tr/a-zÁÉÍÓÚÀÈÌÒÙÄËÏÖÜÂÊÎÔÛÇa-zäëïöüáéíóúàèìòùâèìòùñçßœ/ /cs'

it means: except letters think of, replace character space, , squeeze spaces.

gnu coreutils tr has issues multi-byte characters - considers them sequence of single byte characters instead.

taking account, see on linux "expected":

$ echo – | od -t x1 0000000 e2 80 93 0a 0000004 $ echo ’ | od -t x1 0000000 e2 80 99 0a 0000004 $ echo – | tr ’ x | od -t x1 0000000 58 58 93 0a 0000004

edit:

for set of utf-8 compatible utilities, might want have @ heirloom toolchest. contains tr implementation apparently has utf-8 support, although have not tested it.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
