The six modified files all had spurious characters introduced apparently
as a result of files with the UTF8 BOM marker, U-FFFE, which is
conventionally used at the start of text files to indicate a UTF-8 file
and is invisible under normal circumstances (e.g. the file is opened as
a text file).

None of these files are recognized by espeak-ng on Linux systems because
the 'language variant' line is seen by espeak-ng as starting with a new
character.

'gustave' is an uncorrupted file, it correctly starts with the BOM in
UTF-8 (three bytes), however even though it is correct espeak-ng does
not read it (this may be a separate bug!)

'marcelo' somehow got the BOM character replaced by a literal '?',
notice that 'git diff' on these changes will, indeed, show the removed
character in 'gustave' as a literal '?'.  Notice also that the character
in question, the BOM, is actually the Unicode 'zero width no-break
space', so it is pretty invisible.

The remaining files seem to have suffered major corruption possible as a
result of dostounix style convertions.  The line endings, normally <lf>
on Unix or <cr><lf> on Windows, had been converted to <cr><lf><lf> and
the BOM had been replaced by a <tab> character.
