Message:

Updated the charset loading logic [v1.1.5-testing]

This can now inject custom glyphs at any code-point and optionally
remap the original character somewhere else.

For Spanish, two custom CP850 glyphs, 0xb5 and 0xe0, are used.
And the original glyph at code-point 0xb5, which is a box-character that
AiR-BOOT uses, is remapped to code-point 0xd9.

Translator-build 'AiR-BOOT-v1.1.5-ES-TESTBUILD-20180705' was created
from this commit.

CAUTION:
This is a testbuild !
AirBoot uses the BIOS to access disks and a small coding error can trash
partition tables or other vital disk structures. You are advised to make
backups of TRACK0 and EBRs before using this testbuild. More info at:
