If you use libdevmapper to handle device-mapper devices, have
a look at libdevmapper.h. You can bypass default mangling with
dm_set_name_mangling_mode(DM_STRING_MANGLING_NONE):
---
/*
* Mangling support
*
* Character whitelist: 0-9, A-Z, a-z, #+-.:=@_
* HEX mangling format: \xNN, NN being the hex value of the character.
* (whitelist and format supported by udev)
*/
typedef enum {
DM_STRING_MANGLING_NONE, /* do not mangle at all */
DM_STRING_MANGLING_AUTO, /* mangle only if not already mangled with hex, error when mixed */
DM_STRING_MANGLING_HEX /* always mangle with hex encoding, no matter what the input is */
} dm_string_mangling_t;
/*
* Set/get mangling mode used for device-mapper names and uuids.
*/
int dm_set_name_mangling_mode(dm_string_mangling_t name_mangling);
dm_string_mangling_t dm_get_name_mangling_mode(void);
