11 | // Notes: | |
12 | // | |
13 | // The conversions wxFormatConverter currently does are as follows: | |
14 | // | |
15 | // %s, %lS -> %ls | |
16 | // %S, %hS -> %s | |
17 | // %c, %lC -> %lc | |
18 | // %C, %hC -> %c | |
19 | // | |
20 | // %hs and %hc stay the same. | |
21 | // | |
22 | // %S and %C aren't actually in the ISO C or C++ standards, but they can be | |
23 | // avoided when writing portable code. | |
24 | // | |
25 | // Nor are %hs or %hc in the standards, which means wxWidgets currently doesn't | |
26 | // have a specifier for 'char' types that is ok for all builds and platforms. | |
27 | // | |
28 | // The effect of using %hs/%hc is undefined, though RTLs are quite likely | |
29 | // to just ignore the 'h', so maybe it works as required even though it's | |
30 | // not legal. | |
31 | // | |
32 | // I've put in some checks, such as this which will flag up any platforms | |
33 | // where this is not the case: | |
34 | // | |
35 | // CPPUNIT_ASSERT(wxString::Format(_T("%hs"), "test") == _T("test")); | |
