* QtMiscUtils: add isAsciiPrintable() helperAhmad Samir2023-03-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | - isAsciiPrintable: borrowed the logic from isPrintable(uchar) in qdebug.cpp, now isPrintable(uchar) calls isAsciiPrintable - Replace ::isspace() with ascii_isspace() from qlocale_p.h Functions from ctype.h have a couple of issues: - they're locale-dependent, which isn't what's required here, the code is only interested in ASCII - their args should be representable as uchar or EOF otherwise it's undefined behavior An Early-Warning could use something like: grep -rP "\b(isalnum|isalpha|isblank|iscntrl|isdigit|islower|isgraph|\ "isprint|ispunct|isspace|isupper|isxdigit|tolower|toupper)\b" Pick-to: 6.5 Task-number: QTBUG-111262 Change-Id: I1f47f41bd56735297078ff0d0ddc2ebf999abf8b Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>

* QtMiscUtils: add missing toAsciiUpper(), use it in mocMarc Mutz2022-12-181-0/+5
| | | | | | | | | | | | | | | | | | | | | | ... to make moc code locale-independent. The C toupper function is locale-dependent. Given the right locale (Türkiye, e.g.), toupper('i') is either - İ (LATIN CAPITAL LETTER I WITH DOT ABOVE; if representable) or - i (unchanged; if it isn't) Both results are wrong for the present use-case. Fix by adding QtMiscTools::toAsciiUpper(), complementing existing toAsciiLower(), and using that. It's private API, but moc.h, despite the name, is not a public header.
