A 16-bit character encoding scheme allowing characters from Western European, Eastern European, Cyrillic, Greek, Arabic, Hebrew, Chinese, Japanese, Korean, Thai, Urdu, Hindi and all other major world languages, living and dead, to be encoded in a single character set. The Unicode specification also includes standard compression schemes and a wide range of typesetting information required for worldwide locale support. Symbian OS fully implements Unicode. A 16-bit code to represent the characters used in most of the world's scripts. UTF-8 is an alternative encoding in which one or more 8-bit bytes represents each Unicode character. A 16-bit character set defined by ISO 10646. A code similar to ASCII, used for representing commonly used symbols in a digital form. Unlike ASCII, however, Unicode uses a 16-bit dataspace, and so can support a wide variety of non-Roman alphabets including Cyrillic, Han Chinese, Japanese, Arabic, Korean, Bengali, and so on. Supporting common non-Roman alphabets is of interest to community networks, which may want to promote multicultural aspects of their systems.

Hi,

In the non-unicode each logon language having separate code pages, whereas in in the unicode using single code page for all languages.

unicode is for multilingual capability in SAP system,

apart from that important unicode t.code is uccheck if you give report name we will get different error codes,in genaral we get an error of structures miss match,obsolute statemnts,open data set,describe ststment and so on

more over you can say we delete all obsolute function modules, look at the following it may help you

Before the Unicode error

• lt_hansp = lt_0201-endda0(4) - lt_0002-gbdat0(4).

Solution.

data :abc type i,

def type i.

move lt_0201-endda+0(4) to abc.

move lt_0002-gbdat+0(4) to def.

lt_hansp-endda = abc - def.

Before the Unicode error:

• WRITE: /1 'CO:',CO(110).

Solution.

FIELD-SYMBOLS: <fs_co> type any.

assign co to <fs_co>.

WRITE: /1 'CO:',<fs_co>(110).

DESCIBE002 In Unicode, DESCRIBE LENGTH can only be used with the IN BYTE MODE or IN CHARACTER MODE addition.

Before the Unicode error:

• describe field <tab_feld> length len.

Solution.

describe field <tab_feld> length len IN character mode.

Before the Unicode error:

• DESCRIBE FIELD DOWNTABLA LENGTH LONG.

Solution.

DESCRIBE FIELD DOWNTABLA LENGTH LONG IN byte MODE.

DO 002 Could not specify the access range automatically. This means that you need a RANGE addition

Before the Unicode error:

• DO 7 TIMES VARYING i FROM aktuell(1) NEXT aktuell+1(1)

Solution.

DO 7 TIMES VARYING i FROM aktuell(1) NEXT aktuell+1(1) RANGE aktuell .

Before the Unicode error:

• DO 3 TIMES VARYING textfeld FROM gtx_line1 NEXT gtx_line2.

Solution.

DATA: BEGIN OF text,

gtx_line1 TYPE rp50m-text1,

gtx_line2 TYPE rp50m-text2,

gtx_line3 TYPE rp50m-text3,

END OF text.

DO 3 TIMES VARYING textfeld FROM gtx_line1 NEXT gtx_line2 RANGE text..

Before the Unicode error:

• DO ev_restlen TIMES

• VARYING ev_zeichen FROM ev_hstr(1) NEXT ev_hstr+1(1).

Solution.

DO ev_restlen TIMES

VARYING ev_zeichen FROM ev_hstr(1) NEXT ev_hstr+1(1) range ev_hstr.

MESSAGEG!2 IT_TBTCO and "IT_ALLG" are not mutually convertible. In Unicode programs, "IT_TBTCO" must have the same structure layout as "IT_ALLG", independent of the length of a Unicode character.

Hi,

different languages use different charcter sets. With unicode you can handle this more easy and comfortable. By the way you are forced to use more memory space for one charcter. Unfortunately there is not only one Unicode (UTF8, UTF16). There are standards for unicode. Nevertheless working with unicode in detail may be sophisticated.

regards

Walter Habich
