lib: charset: add u16_strcmp()

2019-09-20T18:09:19+00:00

u16 version of strcmp(): u16_strncmp() works like u16_strcmp() but only
at most n characters (in u16) are compared.
This function will be used in my UEFI secure boot patch.

lib: charset: correct utf8_utf16_strnlen() description

2019-05-12T18:54:21+00:00

Correct the description of utf8_utf16_strnlen() and utf8_utf16_strlen() to
reflect that they return u16 count and not byte count.

For these functions and utf16_utf8_strnlen() describe the handling of
invalid code sequences.

efi_loader: support Unicode text input

2018-09-23T19:55:30+00:00

Up to now the EFI_TEXT_INPUT_PROTOCOL only supported ASCII characters.
With the patch it can consume UTF-8 from the console.

Currently only the serial console and the console can deliver UTF-8.
Local consoles are restricted to ASCII.

efi_loader: rename utf16_strlen, utf16_strnlen

2018-09-23T19:55:29+00:00

The function names utf16_strlen() and utf16_strnlen() are misnomers.
The functions do not count utf-16 characters but non-zero words.
So let's rename them to u16_strlen and u16_strnlen().

In utf16_dup() avoid assignment in if clause.

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.
