Note for kUnicodeUTF16Format and kUnicodeUTF32Format:
- An array of UTF16Char (UniChar) or UTF32Char is normally understood to use "internal" or
platform-native byte ordering for kUnicodeUTF16Format and kUnicodeUTF32Format; the array MAY
begin with byte-order mark (BOM), but the BOM should match the internal ordering.
- If an array of bytes (such as char *) that can be in various encodings is specified to be
in Unicode with kUnicodeUTF16Format or kUnicodeUTF32Format (not explicitly BE or LE), then it
is assumed to use "external" byte ordering, which means: If there is a BOM at the beginning
of text, the BOM specifies the byte ordering, otherwise big-endian is assumed.

Defined feature/fix bits for tecUnicodeConverterFeatures field
Bit: Meaning if set:
---- ---------------
kTECKeepInfoFixBit Unicode Converter no longer ignores other control flags if
kUnicodeKeepInfoBit is set. Bug fix in TEC Manager 1.2.1.
kTECFallbackTextLengthFixBit Unicode Converter honors the *srcConvLen and *destConvLen
returned by caller-supplied fallback handler for any status it
returns except for kTECUnmappableElementErr (previously it only
honored these values if noErr was returned). Bug fix in TEC
Manager 1.2.1.
kTECTextRunBitClearFixBit ConvertFromUnicodeToTextRun & ConvertFromUnicodeToScriptCodeRun
function correctly if the kUnicodeTextRunBit is set (previously
their determination of best target encoding was incorrect). Bug
fix in TEC Manager 1.3.
kTECTextToUnicodeScanFixBit ConvertFromTextToUnicode uses an improved scanner and maintains
some resulting state information, which it uses for mapping.
This has several effects:
- Improved mapping of 0x30-0x39 digits in Mac OS Arabic, fewer
direction overrides when mapping Mac OS Arabic & Hebrew, and
improved mapping of certain characters in Indic encodings.
- Malformed input produces kTextMalformedInputErr.
- ConvertFromTextToUnicode accepts and uses the control flags
kUnicodeKeepInfoMask and kUnicodeStringUnterminatedMask.
Bug fix and enhancement in TEC Manager 1.3.
kTECAddForceASCIIChangesBit Define new control flag bits kUnicodeForceASCIIRangeBit and
kUnicodeNoHalfwidthCharsBit for use with
ConvertFromTextToUnicode, ConvertFromUnicodeToText, etc.
Enhancement in TEC Manager 1.4.
kTECPreferredEncodingFixBit CreateUnicodeToTextRunInfo and related functions fix a problem
that occurred when a preferred encoding was specified that did
not match the System script; the preferred script was not
actually placed first in the ordered list of encodings to use.
Bug fix in TEC Manager 1.4.
kTECAddTextRunHeuristicsBit Define new control flag bit kUnicodeTextRunHeuristicsBit for
use with ConvertFromUnicodeToTextRun.
kTECAddFallbackInterruptBit Define new option kUnicodeFallbackInterruptSafeMask for use
with SetFallbackUnicodeToText. If a client fallback handler is
installed without specifying this bit, ConvertFromUnicodeToText
will HLock the tables it uses (in case the fallback handler
moves memory); otherwise, it won't.
