If you’ve received a text file from another person, or opened a file created on another computer, it may not immediately be readable in EditPad.

Unicode is a standard that aims to encompass all traditional character mappings, and all scripts used by current and historical human languages. You can’t mix Chinese, Russian and French in a text file, unless you use Unicode. In addition to conversion problems, the main problem with using traditional character mappings is that it is impossible to create text files written in multiple languages using multiple scripts.

Since different computer manufacturers had different ideas about how to create character mappings, there’s a wide variety of legacy character mappings. As a result, different character mappings are used for different languages and scripts. This means that only 256 distinct characters can be represented in any text file.

Traditional character mappings or code pages use only 8 bits per character. When saving a file in one application, and opening that file in another application, both applications need to use the same character mappings. When you open a text file, the numbers are read and mapped back to characters. When you save a text file, each character is mapped to a number, and the numbers are stored on disk. If data is being used through the web application then up conversion can be handled by client application using appropriate encoding.Convert|Text Encoding Convert|Text EncodingĬomputers deal with numbers, not with characters. from VARCHAR to NVARCHAR back to original value, just need to export it back again to flat file and importĪgain in NARCHAR column and it will retain the original valueĥ.

If there is a need to up convert the data from UTF-8 to UTF -16 i.e. Import the exported flat file in to new table and it should be successful but original Data will look different like shown below based on the column collation.Ĥ. separate table with VARCHAR column for NVARCHAR column data)ģ. Create new table with similar schema but replace Unicode column data type with non-Unicode data column (i.e. Use SQL import export wizard (?) to export Unicode data to UTF8, using code page 65001 to flat file destinationĢ. To obtain the original Unicode value one can up convert this VARCHAR data back into NVARCHAR data using specific code page and importingĮxported flat file back into Unicode column.ġ. Only difference is the data in VARCHAR column will look like garbage because of native data character set conversion,īut will retain original value based on collation setting for the object. Non-Unicode format (also can save resulting SSIS package for further use) and import that back to SQL Server table in table with VARCHAR column. In SQL Server 2012 there is a support for code page 65001, so one can use import export wizard quickly to export data from SQL table to

This can be achieved by first exporting Unicode data to a file with code page 65001 (Down convert) and then import back in to VARXHAR column With code page 65001 (Down convert) and also import back in to column with VARCHAR data type in SQL table (Up convert). it is possible to export Unicode data to file Good news is SQL Server 2012 supports porting of data from UTF16 – UTF 8 encoding. Given above using SQL Server versions mentioned above Due to this limitation, it is impossible to port Unicode data from NVARCHAR column to VARCHAR column without losing special characters. To move data between UTF16 – UTF8 encoding without losing data. Little tricky part is SQL Server after 2005 to SQL Server 2008 R2 does not support code page 65001 (UTF-8 encoding) and making it difficult , COLLATIONPROPERTY (, 'ComparisonStyle' ) AS Below query will give details onĪll the supported code pages in SQL Server.

MS SQL Server by default supports Code 2 (ISO Character Set - SQL_Latin1_General_CP1_CI_AS) but it differs in how it implements other code pages related to other ISO standards. Unicode data in SQL Server or flat file source if ported to SQL server table in a VARCHAR column, using SSIS, BCP or any other mean will During data conversion, it can be observed that the Unicode characters getting converted to ‘?’ instead of retaining its Unicode data meaning in the destination. In SQL server, few specific data handling scenarios require Unicode source data to be moved to non-Unicode destination format like ASCIIįormat.
