Naming conventions for code pages

All AFP code page names begin with T1, which makes them recognizable as code pages. This topic shows the naming conventions for code pages and extended code pages that are used with these font library character sets:

General Library (outline fonts) and SBCS (expanded core raster fonts)
CJK (outline fonts) and DBCS (core raster fonts) with full-width characters
CJK (outline fonts) and DBCS (core raster fonts) with half-width characters

Code pages for General Library and SBCS fonts

The last six characters of the code page name are used to identify the code page for General Library and SBCS fonts. The preferred naming convention is where the first two characters are 00, V1, or B0, and the final four characters are the code page global identifier (CPGID), which is a number that is registered by IBM® to uniquely identify each code page.

Table 1 shows the naming convention for code pages that are used with General Library outline font character sets and SBCS raster font character sets. The naming convention format is T1yyyyyy.

Table 1. Naming convention for General Library and SBCS fonts
T1	`yyyyyy`
AFP code page prefix	Code page identifier: 00`nnnn` Expanded core code pages; `nnnn` is the CPGID. V1`nnnn` Expanded core code pages; `nnnn` is the CPGID. B00`nnn` BookMaster code pages; 0`nnn` is the CPGID. D`xnnnn` DCF-related code pages D`x`BASE Migration code pages GDP`nnn` Data processing code pages GE0`nnn` Sonoran Display and Sonoran Petite code pages GI0`nnn` General code pages GP0`nnn` General-purpose code pages L0`nnnn` LCS-related code pages M00`nnn` Mathematics code pages S0`nnnn` 6670-related code pages SKB`nnn` Standard keyboard code pages

Code pages with full-width characters for CJK and DBCS fonts

The names of code pages that use full-width characters are typically six characters for CJK outline fonts and eight characters for DBCS raster fonts.

Table 2 shows the naming convention for code pages that are used with CJK and DBCS full-width character sets. The naming convention format is T1xxxxss.

T1	`xxxx`	`ss`
AFP code page prefix	Code page global identifier (CPGID), with these exceptions 0300 Japanese JIS X 0213:2000 code page for CPGID:65280 K300 Japanese JIS X 0213:2004 code page for CPGID:0300 I300 Japanese IBM JIKEI code page for CPGID:65281 J300 Japanese IBM JIKEI with JIS90 code page is for CPGID:65282 0834 Korean KS code page for CPGID:65283 K834 Korean Full Hangul code page for CPGID:0834 0835 Traditional Chinese code page for CPGID:0835 0837 Simplified Chinese GB code page for CPGID:65284 K837 Simplified Chinese GB18030 code page is for CPGID:0837	Section number for a code page that is used with a raster font.

Code pages with half-width characters for CJK and DBCS fonts

The names of code pages that use half-width characters typically have H0 as the third and fourth characters.

Table 3 shows the naming convention for code pages that are used with CJK and DBCS half-width character sets. The naming convention format is T1Hnxxxx.
