Interface: CharsetPage

Defined in: packages/core/src/charset/pages.ts:25

A pluggable charset codec, matched by name against Firebird charset names and user-facing encoding options.

Properties

Property	Type	Description	Defined in
maxBytesPerChar	number	Wire bytes per character — sizes CHAR/VARCHAR buffers. 1 for single-byte pages.	packages/core/src/charset/pages.ts:33
names	string[]	Primary name first, then aliases. Matching is case-insensitive and ignores -, _ and spaces, so ['WIN1252', 'CP1252'] also matches "win-1252" or "cp_1252".	packages/core/src/charset/pages.ts:31

Methods

createStreamDecoder()?

optional createStreamDecoder(onError?): CharsetStreamDecoder;

Defined in: packages/core/src/charset/pages.ts:38

Chunk-safe decoding for large blobs. Single-byte pages get a stateless one from the helper.

Parameters

Parameter	Type
onError?	DecodeErrorMode

Returns

CharsetStreamDecoder

---

decode()

decode(buf, onError?): string;

Defined in: packages/core/src/charset/pages.ts:34

Parameters

Parameter	Type
buf	Buffer
onError?	DecodeErrorMode

Returns

string

---

encode()

encode(value): Buffer;

Defined in: packages/core/src/charset/pages.ts:36

Mandatory: a decode-only page would fail at the first bound parameter. Unmappable characters become ?.

Parameters

Parameter	Type
value	string

Returns

Buffer
