Bug ID: 30382
Summary: Add LD option for using UTF-8 code page in generated
Windows PE binaries
Product: binutils
Version: 2.39
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: pali at kernel dot org
Target Milestone: ---
Windows PE binaries generated by LD use by default legacy code page (e.g.
CP1252) when working with any char* WinAPI function, including argv[] arguments
in main.
Legacy code pages do not support whole range of UNICODE characters and
therefore passing non-ASCII filename via argv[] to main() loose processing of
command line arguments.
UTF-8 is now widely used, so LD should support generating Windows PE binaries
in a way that are marked as UTF-8 compatible. Windows OS then will use UTF-8 as
code page for all char* WinAPI function and will pass argv[] to main() in UTF-8
too.
Switching code page to specific one for Windows PE binary is done by adding
activeCodePage element into manifest.
So please add some LD switch --active-code-page= for specifying code page which
will be put into the final generated Windows PE binary.
It should be considered for future that LD sets this --active-code-page=
automatically to UTF-8 by default for all Windows PE binaries as usage of
legacy code pages in application runtime is nowadays in UTF-8 ere just legacy.
Please note that LD currently does not support manifests at all:
