3. 3 Problem: We would like to add a phonograph symbol as a prefix to the display of the subfield {2xx}$$p we would need to use the Unicode U+2117 in edit_field.lng which is currently outside the available codes that can be used in this table. This is being considered for use in MARC21 in order to comply with RDA rules

4. 4 Suggested configuration: Indeed in edit_field.lng table it is problematic to enter some actual Unicode characters, but there is a configuration to achieve this. The configuration is to use a regular letter from the Latin character set and make it become the unicode value that we need We will now describe this configuration

5. 5 Step One In $alephe_root/unicode directory create the following character conversion table This means that in table bl_to_unicode the Z (Unicode value 5A becomes the phonograph symbol

6. 6 Step Two Now in tab_character_conversion_line we will make reference to the bl_to_unicode table This means that character conversion BL_TO_UTF will use the values defined in table $alephe_uniocode/bl_to_unicode.

7. 7 Step Three Now we need to add the appropriate character conversion line before the phonograph symbol (2117) will be converted from Z (5A) We also need to disable the character conversion after the Z is converted to the phonograph symbol, otherwise every Z will become the phonograph symbol. Therefore in the line after the conversion of Z to phonograph symbol we will use the default char-conv table which is 8859_1_to_utf.

8. 8 Step Three For example, we created the following setup in edit_field.eng: Here we state the Z should convert to phonograph symbol Here we state that the character conversion should return “back to normal”

9. 9 Step Four System number 65738 has field 24514$$p:

10. 10 Step Five In the full view of this record in web OPAC we can see this symbol is being added:

11. 11 The Unicode Value in templates It is also possible to add the Unicode value characters to cataloging templates For example if we want to add the Euro value to a cataloging template we can first add it to $alephe_unicode/bl_to_unicode yoelk@il-aleph07(a20_3) USM01> cat bl_to_unicode !!-!!-!!-!!-!!-!!-!!-!!-!!-!!!! 5A 2117 #Z will become SOUND RECORDING COPYRIGHT 59 20AC #Y will become Euro sign yoelk@il-aleph07(a20_3) USM01> This is YThis is a Euro

12. 12 The Unicode Value in templates Here is a Y in the cataloging template using the special conversion 2451 L $$a $$b $$c $$h CHARACTER_CONVERSION=BL_TO_UTF 246 L $$a The symbol Y and the future of the European Union CHARACTER_CONVERSION=8859_1_TO_UTF 250 L $$a $$b
