As has been pointed out, this is probably only valid from France.

SS#7 has language bits, but they seem to be used mainly to indicate to
the called country's operators in which language they should reply to
calling operators.  I don't know whether this is used in any other
part of SS#7, but it's the only place I've seen a reference to
languages in SS#7 proper.  There is a pointer to Q.104, which I don't
have access to, titled "Language digits or discriminating digits", to
which the 001001 code below refers.  For curiosity, the following bit
patterns and languages are supported with the calling party category
field of the initial address message:

	000000 unknown source
	000001 operator, language French
	000010 operator, language English
	000011 operator, language German
	000100 operator, language Russian
	000101 operator, language Spanish
	000110 \  Available to administrations for
	000111  > selecting a particular language
	001000 /  provided by mutual agreement
	001001 reserved  (may be used to indicate national operator)
	001010 ordinary calling subscriber
	001011 calling subscrier with priority
	001100 data call
	001101 test call
	001110 spare
	001111 payphone
	010000 \
	 thru   > spare
	111111 /

(This is CCITT recommendation Q.723 (1988) section 3.3.1 d).)

Ah, the wonders of reading specs from start to end... :-)
