A brief terminology clarification: the BOM is by definition one
"character". When encoded as UTF-8, it is represented by three bytes
with the decimal values you gave. The AppleScript term "ASCII
character" is thus doubly a misnomer here.
In bash you can output arbitrary bytes by using the -e ("honor Escape
sequences") option to the echo command and putting backslash octal
escapes in the string. Decimal 239 is octal 357;decimal 187 is octal
273; and decimal 191 is octal 277. So you can output a BOM with this
command:
echo -ne '\357\273\277'
(The -n prevents echo from adding a newline after the bom)
