I see this problem ("Enables" renders as "Enable ~U" because the "s"
is actually UTF-8 D195, CYRILLIC SMALL LETTER DZE).
"file" found the following other Kconfig files that also contain
UTF-8:
drivers/pci/Kconfig
D195 CYRILLIC SMALL LETTER DZE, which looks like "s"
"Enables" renders as "Enable ~U"
net/netfilter/ipvs/Kconfig
C2A0 NO-BREAK SPACE
renders fine
drivers/mtd/nand/raw/Kconfig
MTD_NAND_CAFE C389 LATIN CAPITAL LETTER E WITH ACUTE
"CAFÉ" renders as "CAF ~I"
drivers/mtd/spi-nor/Kconfig
MTD_SPI_NOR_USE_4K_SECTORS
"16 × 4 KiB" renders as "16 ~W 4 KiB"
drivers/net/can/usb/Kconfig
drivers/net/can/peak_canfd/Kconfig
drivers/gpu/drm/panel/Kconfig
drivers/platform/mellanox/Kconfig
kernel/time/Kconfig
crypto/Kconfig
arch/Kconfig
Some of these are clearly wrong (Cyrillic letter), some are
unnecessary (non-breakable space), some are arguable ("CAFÉ" and "16 ×
4 KiB" -- these take advantage of UTF-8 in useful ways).
Not being a charset guru, I dunno if the rendering problem means
my terminal is set incorrectly or if they all need to be changed.
But I think we should address all of them at the same time. If we do
need to avoid UTF-8 in Kconfig help, maybe checkpatch should look for
it.
