correctly. This doesn't slow down the loading of PS fonts significantly since charstrings aren't affected. * include/freetype/config/ftstdlib.h (ft_xdigit): Renamed to... (ft_isxdigit): This. Updated all callers. (ft_isdigit): New alias to `isdigit'. * include/freetype/internal/psaux.h (PS_Parser_FuncsRec): Renamed `skip_alpha' to `skip_PS_token'. Add parameter to `to_bytes' and change some argument types. * src/psaux/psauxmod.c (ps_parser_funcs): Updated. * src/psaux/psobjs.c (ft_char_table): New array to map character codes (ASCII and EBCDIC) of digits to numbers. (OP): New auxiliary macro holding either `>=' or `<' depending on the character encoding. (skip_comment): New function. (skip_spaces): Use it. (skip_alpha): Removed. (skip_literal_string, skip_string): New functions. (ps_parser_skip_PS_token): New function. This is a better replacement of... (ps_parser_skip_alpha): Removed. (ps_parser_to_token, ps+parser_to_token_array): Updated. (T1Radix): Rewritten, using `ft_char_table'. (t1_toint): Renamed to... (ps_toint): This. Update all callers. Use `ft_char_table'. (ps_tobytes): Add parameter to handle delimiters and change some argument types. Use `ft_char_table'. (t1_tofixed): Renamed to... (ps_tofixed): This. Update all callers. Use `ft_char_table'. (t1_tocoordarray): Renamed and updated to... (ps_tocoordarray): This. Update all callers. (t1_tofixedarray): Renamed and updated to... (ps_tofixedarray): This. Update all callers. (t1_tobool): Renamed to... (ps_tobool): This. Update all callers. (ps_parser_load_field): Updated. (ps_parser_load_field_table): Use `T1_MAX_TABLE_ELEMENTS' everywhere. (ps_parser_to_int, ps_parser_to_fixed, ps_parser_to_coord_array, ps_parser_to_fixed_array): Skip spaces. Updated. (ps_parser_to_bytes): Add parameter to handle delimiters and change some argument types. Updated. * src/psaux/psobjs.h: Updated. * src/cid/cidload.c (cid_parse_dict): Updated. * src/cid/cidparse.c (cid_parser_new): Check whether the `StartData' token was really found. * src/cid/cidparse.h (cid_parser_skip_alpha): Updated and renamed to... (cid_parser_skip_PS_token): This. * src/type1/t1parse.h (T1_ParserRec): Use `FT_Bool' for boolean fields. (T1_Skip_Alpha): Replaced with... (T1_Skip_PS_Token): This new macro. * src/type1/t1parse.c (hexa_value): Removed. (T1_Get_Private_Dict): Use `ft_isxdigit' and `psaux->ps_parser_funcs_to_bytes' for handling ASCII hexadecimal encoding. After decrypting, replace the four random bytes at the beginning with whitespace. * src/type1/t1load.c (t1_allocate_blend): Use proper error values. (parser_blend_design_positions, parse_blend_design_map, parse_weight_vector): Updated. (is_space): Handle `\f' also. (is_name_char): Removed. (read_binary_data): Updated. (parse_encoding): Use `ft_isdigit'. Updated. (parse_subrs): Updated. (TABLE_EXTEND): New macro. (parse_charstrings): Updated. Provide a workaround for buggy fonts which have more entries in the /CharStrings dictionary then expected; the function now adds some slots and skips entries which still exceed the new limit. (parse_dict): Updated. Terminate on the token `closefile'. * src/type42/t42parse.c (T1_Skip_Alpha): Replaced with... (T1_Skip_PS_Token): This new macro. Updated all callers. (t42_parse_encoding): Use `ft_isdigit'. * src/base/ftmm.c (ft_face_get_mm_service): Return FT_Err_OK if success.
